Eight frequently asked questions about concrete

Eight frequently asked questions about concrete

Concrete is one of the most popular building materials across the globe. It is used in most construction projects, along with other cement-based materials such as plaster and mortar. Here are eight frequently asked questions about concrete that can shed some light on the material for people wanting to know more or become contractors themselves.

1. Are cement and concrete the same thing?

No, cement and concrete are not the same. Cement is a main ingredient of concrete and comes in a dry powder form. Together with water and aggregates (usually rock, gravel or sand) cement is used to make concrete. As a part of concrete, cement is the binding agent that holds the mixture together.

2. How long does it take for concrete to become hard, or set?

It takes 24 – 48 hours for concrete to set. Concrete will achieve 70% of its full strength seven days after it was laid. It will reach its full strength (100%) 28 days after it was laid. Concrete will become increasingly stronger over time because the cement forms bonds with surrounding moisture particles.

3. What are the ingredients of concrete?

Concrete is made up of cement, water and aggregates (sand or crushed stone). Cement is a dry powder made by LafargeHolcim Tanzania. Cement is the binding agent that holds the mixture together. Water is needed to form a chemical reaction with the cement. The water/cement ratio will determine the strength of the concrete. Aggregates can be either gravel, rocks or sand. It gives the concrete its structural volume and strength.

4. Can I lay concrete in wet weather?

Yes, it is possible to lay concrete when it is raining, but proper preparation is necessary. Precipitation (rain, snow, sleet, or hail that falls to or condenses on the ground) can lead to concrete becoming soft, which could reduce its strength. Constructing a protective enclosure of wood and plastic sheeting around the area where the concrete will be laid can prevent this type of damage.

5. What is concrete’s durability?

Concrete is extremely durable. It is a high-strength product and its traits make it suitable to be used in a number of ways, from industrial to domestic. Concrete has a lifespan of 40 years or more and it also hardens with age.

6. Is concrete an eco-friendly material?

Concrete is sourced from natural rock and often extracted on location, which means that minimal resources are needed to transport it to the required work site. At the end of its lifespan, concrete can be crushed and recycled. So, while it is not traditionally classed as an environmentally-friendly material, there are eco-friendly elements to concrete’s creation.

7. Will my floors be cold if they are made from concrete?

While concrete floors can be cold, they are not much colder than other often-used materials like natural stone flooring or ceramic tiles. During hot summer months, cooler floors can be a bonus and contribute to lower air conditioning costs – especially in a country like Tanzania where hot weather can be experienced all year-round.

8. How do I calculate the amount of concrete my project requires?

It is simple to calculate the amount of concrete needed for your project. Here’s an article that outlines the process of estimating the volume of concrete needed for any project, based on its area and volume.

What is a construction consultant and what do they do?

Construction consultant at work on site

A consultant is someone who offers expert or professional advice in a particular field. They provide this service of expertise to either a company or an individual client, charging a professional fee for their services. A construction consultant is an experienced expert in the construction industry who can offer clients valuable advice and share expert knowledge that the client may lack.

A construction consultant can work in various aspects of the building industry. This includes project management, contracts, surveying, architecture, analysis, construction management and so on. The administration of the consultant’s work contract is the responsibility of the client.

A construction consultant must offer his or her clients:

  1. A perfectly clear definition of the project and what it entails.
  2. Advice and guidance on how the project should be set up.
  3. Development and coordination of the project design.
  4. Collecting and preparing the product information and documents for tender.
  5. Inspection and correction of contractors’ work.

Consultants perform an extensive analysis of their projects

For example, civil engineering professionals provide their services as consultants for engineering consulting companies. These experts plan, design and execute buildings, highways, water treatment plants, airports, railroads and more. Civil engineering consultants must perform an extensive analysis of the structure that they will work on. They must also analyse environmental factors, ensuring that the final structure is safe, sustainable, functional and durable.

It is the consultant’s job to select the best, most economical materials and methods of construction in order to perform the project. Consultants must give priority to what the client wants, as well as take their views into account. The client chooses the consultant based on the type of project and its requirements.

Construction consultants are hired for their particular expertise

If the project requires the design of reservoirs and the maintenance of rivers and coastal areas, consultants in hydraulics civil engineering will be hired for their expertise. To create buildings that will safely perform its functions in all types of weather, structural engineers will consult on the project.

In order to be a construction consultant, you will need a graduation degree in civil engineering. You will also need to have sufficient knowledge of physics, maths, structural design and project management. It will also be an advantage to know the relevant software packages and to be able to develop structural drawings.

When they work as consultants, civil engineers earn a high income compared to civil engineers working in other industries or government agencies. Established construction companies also offer regular training and courses to keep engineers up-to-date with the latest innovations in the industry.

Once a construction professional has gained a sufficient amount of working experience, they can start a career as a freelance consultant working in the construction industry.

The following services are offered by civil engineering construction companies:

  • Structural design
  • Civil and environmental services
  • Site development
  • Surveying
  • Environmentally-safe construction
  • Energy-saving equipment
  • Energy-saving methods
