Architect visits two Tanzanian universities

Pieter Mathews shares architectural knowledge with Tanzanian students

Award-winning South African architect, Pieter Mathews, visited two local universities with LafargeHolcim Tanzania during his recent visit to the country. Mathews shared valuable knowledge and insights into the architecture industry with students at Ardhi University and the University of Dar es Salaam. His focus was on the use of concrete and its various applications for architecture and construction.

Mathews also shared some innovative architectural concepts with the eager students at the universities. His company, Mathews and Associates Architects (MAAA), is based in Pretoria, South Africa. The firm has worked on numerous buildings, sculptures and public spaces that have won international awards and recognition. The students were also taught about the LafargeHolcim Tanzania product offerings.

University visits were well received

Mathews and the LafargeHolcim Tanzania team took a tour of the Ardhi University campus in Dar es Salaam before meeting the students. Around 300 students and 10 of their lecturers attended Mathews’ presentation on concrete and architecture.

The team then visited the University of Dar es Salaam’s College of Engineering Technology (COET) campus. Mathews and LafargeHolcim Tanzania visited the engineering laboratory at COET before giving the presentation to 100 architecture students. Architecture is a brand new course at COET; this year will see the first set of graduates qualify from the college.

LafargeHolcim Tanzania was the first company to share industry insights with COET students. Students and lecturers at both universities were inspired by Mathews’ presentation – the universities have asked for more training sessions and similar discussions to take place in the future.

LafargeHolcim Tanzania is always looking for ways to empower communities and advance the construction industry in the country. University visits and presentations are a great way to show students the real-world possibilities of engineering, construction and architecture.

How does concrete choice affect building resilience

Building resilience through concrete

There are many types of concrete for builders to choose from, all of which have different applications for construction. Some types of concrete are more water resistant than others and some have better insulation properties. It all depends on the type of cement used, the aggregate-to-water ratio and any extra additives that may be put in the mixture.

Contractors have an important decision to make when choosing the right type of concrete for a building. This choice can affect the resilience and durability of a building. Homes in fire-prone areas will be built with fire-resistant concrete, whereas those in flood-prone regions might have better water-resistance.

Important buildings such as hospitals, police stations and government facilities will be built to high resilience standards. These key points will need to be protected from severe weather and stand the test of time by being highly durable. The concrete choice will be a key factor, here.

Building material selection is important for resilience

The choice of what building materials to use usually starts with the architect or designer of a building. They decide whether the structure will be built from glass, wood, steel, brick or concrete. All of these materials have different strengths and weaknesses, so the architect will often consult with a civil engineer to make the best choice.

Out of all of these building material choices, concrete is probably the best all-round. That is why concrete is one of the most common materials used in buildings today. It is strong, can be made into any shape or size, does not rot or rust and it can withstand floods and fires.

Concrete is also a good insulator and it is recyclable (it can be broken down and reused as rubble for other building projects). It requires very little maintenance and it is created from common elements found around the world; water, gravel, sand and stone. Concrete can often give a structure the best combination of strength, resilience and security.

Best applications of concrete for resilience

The table below outlines a few natural disasters and what type of concrete is best for building protection:

LafargeHolcim Tanzania: the foundation for sustainable road construction

Road construction in Taznania

LafargeHolcim Tanzania has had a strong impact on the local communities living in the country through our building materials and cement products. We work alongside communities, contractors and local governments to invest in infrastructure and improve the quality of buildings in Tanzania.

One of the current projects that we have been working on is the road upgrade from Sumbawanga to Kasanga Port via Mtai. LafargeHolcim Tanzania has been chosen as the cement supplier for this 122 kilometre stretch of road that will be completed to international standards.

Our Tembo SupaSet and FastaPlus cement products have been supplied in bulk deliveries to the contractors. Approximately 5000 tonnes of cement have been delivered on-time to keep the project running smoothly. LafargeHolcim also offers value-added services such as bulk storage containers and silos to keep the cement dry.

To date, a new layer of asphalt bitumen has already been spread over about 100km of the road. Contractors have stabilised the base of the road to upgrade its load-bearing capacity so that it can support heavy trucks and vehicles travelling to the Kasanga Port on Lake Tanganyika.

This road upgrade will lead to an improvement for the local economy as more goods can be shipped to and from the port. The surrounding communities will benefit from jobs and improved access to the area.

How to prepare for a concrete pour

How to prepare for a concrete pour

There is a fair amount of planning and organisation that needs to be done before concrete is poured at a construction site. This planning will ensure that the pour runs smoothly and that there are no problems.

Planning is essential in the construction industry. It helps contractors to avoid unnecessary costs, wasting time and delaying deadlines. When it comes to pouring concrete, the process needs to be done quickly, smoothly and without injury to any contractors. Once mixed and poured, concrete begins to set, so any delays or problems will result in a costly repair job.

Contractors and workers need to be organised, the pour site needs to be ready and risk control management steps need to be taken to ensure a successful concrete pour. Whether you mix the concrete yourself or have it delivered, here are some steps that need to be taken before concrete is poured.

  • Create an agenda – This document must be given to all employees so that everyone on the construction site knows what the plan is. Confirm that the agenda works for all parties involved. Take into account changes in the weather, equipment breakdowns, employee absenteeism and the concrete supplier’s requirements.
  • Schedule meetings beforehand – Meet with all the construction crews to discuss the plan and find out what equipment will be needed for the pour. Ensure that everyone has read the agenda at the meeting and check that all contractors are ready for the concrete pour.
  • Communicate with your concrete supplier – On the day of the pour and a few days leading up to the event, check with the supplier that they are ready and still on-time with the delivery of the concrete. Check that the order is correct and that the right type of concrete will be delivered.
  • Check the construction site – Walk around the construction site before the concrete arrives. Make sure that the entry is accessible and that there is a clear route to the pour site for the delivery vehicles. Check that the ground is stable and clear from any other building material and tools. Ensure that there is an alternative exit route available if needed. Place signs around the construction site if you think they will be needed.
  • Check your equipment – Make sure all necessary equipment is ready and in the proper position. Check that it all works before the pour and ask contractors if they have all the tools they need for the job, such as pumps, shovels and floats.
  • Perform a safety analysisLook at the potential risks around the site and take steps to minimise any possibility of injury or damage. Remove all trip, slip and fall hazards. Inspect the contractors and ensure that they all have the right safety gear (hard hats, goggles, gloves and boots). Check that all supervisors are ready and in place.

Once these steps have been taken, the concrete pour can take place when all site workers are ready and know what to do. This planning is essential for a safe and efficient construction site. It will also ensure that the concrete pour goes according to plan and no unnecessary costs are incurred.

How to test compressive strength of concrete

Compressive strength test concrete cylinders

Concrete mixtures can have different strength, durability and performance abilities, depending on the type of aggregates and cement used. This means that various concrete mixtures are suited to different applications and structures. The strength of a concrete mixture can be determined by a compressive test.

This test involves placing a cylinder of dry concrete underneath a hydraulic press. The concrete is crushed by the press and the strength of the mixture is calculated when the concrete gives way. This type of test is regularly performed by engineers and cement manufacturers as they research stronger concrete mixtures.

What is the compressive strength of concrete?

The compressive strength of concrete is a numerical value calculated in megapascals (MPa). Compressive strength requirements range from 17 MPa for general purpose concrete to 70MPa for large load-bearing structures such as bridges. It is important to work out the compressive strength of concrete mixtures to ensure that the concrete will be ideally suited to the job.

In most cases, the test cylinders of concrete have been left to cure for 28 days before being placed in the hydraulic press. Two or three concrete cylinders are tested and the average of the results is then determined to be the compressive strength of the concrete mix.

How to test the compressive strength of concrete

The concrete cylinders used for the compressive strength test have standardised dimensions of 150mm by 300mm or 100mm by 200mm. The smaller dimension is the diameter of the cylinder, the larger dimension is the height of the cylinder. These standard dimensions ensure that the same volume of concrete is tested, no matter where in the world they take place.

The concrete cylinders are then weighed and capped with either sulphur mortar or a neoprene pad. These caps provide a flat surface and a bit of protection for the hydraulic press plates. They do not affect the compressive strength reading.

The cylinders are loaded into the centre of the hydraulic press one at a time. They are then compressed until the concrete fails. The type of break is important to note – does the concrete cylinder crack down the middle or do the edges give way first? The most common type of break is a conical fracture where the middle section of the concrete breaks away, leaving behind two cones of concrete at the top and bottom of the cylinder.

The compressive strength is calculated by dividing the maximum load at the failure by the average cross-sectional area of the cylinder. At least two cylinders are tested and the average compressive strength is calculated to the nearest 0.1MPa.

Some concrete mixtures are tested at three or seven days to determine the early strength capabilities of the batch. These early tests are particularly important for concrete that requires early strength, such as arches and pillars. The results of compressive strength tests allow cement manufacturers and contractors to ensure that the right concrete is used for the right structure.
