Concrete is one of the preferred building materials. It is used in almost all construction projects such as residential, commercial, industrial and infrastructure. The demand for concrete is growing due to increasing population and urbanization. However, the conventional concrete production method emits CO2, a greenhouse gas that contributes to global warming. In addition to its contribution to global warming, the production of concrete also consumes a huge amount of energy (about 240 million tons of coal per year) and produces about 1 ton of CO2 for every ton of concrete produced. A green concrete would therefore emit less CO2 and consume less energy during its production than conventional concrete.

A green concrete is a concrete that has low carbon footprint and consumes less energy during its production. A green concrete has several names such as sustainable concrete, eco-concrete, carbon neutral concrete and low carbon footprint concrete. The main attributes of green concrete are:

It contains more by-products and recycled materials than conventional concrete;

It produces less CO2 during its production;

It consumes less energy during its production

Why should I use green concrete?

Green concrete is a revolutionary product that has a lot of benefits from the environmental and economical point of view. The principal raw materials of the green concrete are fly ash, slag and limestone powder.

The most important benefit of this type of concrete is that it reduces the amount of natural aggregates needed for the production of normal concrete. This means that using this kind of concrete we reduce the quantity of CO2 released in the atmosphere by half.

Another great benefit is that it reduces significantly the micro cracks due to thermal expansion or contraction. Green concrete provides a better resistance to sulphate attack, reduces shrinkage and increases durability.

The reduction of the shrinkage is due to the fact that Green Concrete contains less water than traditional concrete. In addition, it can be used in all applications where normal concrete can be used (e.g., foundations). Another advantage of this type of concrete is that it exhibits better workability.

The main attributes of green concrete are:

• High mechanical strength

• Low shrinkage and creep

• Resistance against aggressive environments

• Durability

• Saving the environment from carbon dioxide emissions.

The durability and properties of concrete can be improved by using materials that have less environmental impact, using less cement or using supplementary cementitious materials (SCMs). The production of Portland cement is a major source of carbon dioxide, accounting for approximately 7% of the world’s total CO2 emissions. In addition to producing cement, it requires approximately 120 MJ/tonne energy to produce other components such as aggregates, water, etc.

Concrete is used for most of the buildings, roads and bridges we see around us. The production of this material requires a lot of energy and produces carbon dioxide.

Green concrete is an ideal solution for reducing the environmental impact of this material. You might wonder why you should use green concrete. Here are some arguments to convince you:

1. CO2 reduction: green concrete reduces CO2 emissions by up to 70%.

2. Energy saving: green concrete uses less energy during production than traditional concrete. This saves you money on your heating bill in winter and keeps your house cool in summer.

3. Thermal mass: green concrete has a high thermal mass, which means it stores heat and releases it slowly over time. This makes it perfect for buildings that need to maintain constant temperatures such as hospitals or schools.

4. Durability: green concrete is more durable than traditional concrete because it contains less water and therefore expands less when exposed to moisture or freezing temperatures (which causes cracking). If properly maintained with regular inspections every three years, then this can last up to 100 years without any major problems (such as structural damage due to cracks).

Green concrete is a concept of thinking environmentally for the application and development of concrete structures. It is also a way to conserve energy and natural resources. Through this blog, I would like to explain why green concrete is important. I will cover topics like its advantages, disadvantages, and the future of green concrete.

Concrete has a wide range of uses in the construction industry. The main ingredient of concrete is cement. Cement can be considered as the most important construction material used today. Due to the high demand for cement, there has been an increase in cement production which has resulted in about 5% of global carbon dioxide (CO2) emissions. In addition, all other stages in a building’s life cycle from production to demolition consume energy and cause CO2 emissions. To overcome this problem, green concrete comes into picture as it has many advantages when compared to the normal concrete.

Advantages:

1) Green concrete reduces harmful gases such as CO2 released into the atmosphere during its production making it environment-friendly.

2) It helps in conserving natural resources such as water and river sand by substituting it with industrial waste products such as fly ash, slag sand, quarry dust etc..

3) Reduces wastes going to landfills

What is green concrete?

1. Green concrete is a concrete that uses less water, CO2 and energy, and contains more recycled material than conventional concrete. It’s also called sustainable concrete.

2. A green concrete has a reduced carbon footprint compared to conventional concretes.

The production and transport of cement, the main ingredient of concrete, accounts for 5-10% of the world’s CO2 emissions. The use of recycled materials in the production of new concrete reduces the need for virgin materials, as well as reduces the total emissions associated with its production.

3. Reducing the amount of water in a concrete mix also reduces CO2 emissions by reducing the need for mixing and transporting water, while using less energy to produce greener concretes helps reduce energy costs and emissions further.

Green concrete is a concrete that has had extra steps taken in the mix design and placement to insure a sustainable structure and a long life cycle with a low maintenance surface. The most common example would be to use a high fly ash content instead of portland cement. This will make the concrete stronger, more durable, require less water, and have less environmental impact than conventional concrete.

There are many other components that can be added or removed from the concrete mix to make it green. The use of recycled materials for coarse and fine aggregates can reduce the environmental impact of mining for virgin aggregates. Fly ash is a recycled material that can replace portland cement which is an energy intensive product to produce. Other pozzolanic materials such as silica fume and slag cement can increase strength, reduce permeability, and improve freeze/thaw durability. The use of fresh water can be reduced by adding admixtures that increase water demand slightly while reducing bleed water. This allows for lower w/cm ratios while maintaining proper workability.

The most important aspect of any green concrete is how it performs over time. A green concrete that fails in 40 years will likely have had a greater environmental impact than one with conventional materials that lasts 80 years. We need to take into consideration
