Instead of curing (hardening) the cement in the concrete with water, Solidia injects CO 2 into the concrete. The CO 2 reacts with the cement where it is permanently stored. Solidia claims that this could reduce carbon emissions from cement by a minimum of 1.5 billion tonnes of CO 2 per year. And at the same time, the curing process takes only ...

Based on the ratio of 1: 4, the cement will need 0.5 cu. m, and sand - 2 cu. m; Cube m cement weighs about 1300 kg, cubic meters. m of sand - 1600 kg. At 100 square meters. m area you need 1300 * 0.5 = 650 kg of cement and 1600 * 2 = 3200 kg of sand. So, for 1 square. m screed thickness of 5 cm will need 6.5 kg of cement. In bags, usually 50 kg.

Ratio of water and cement is known as water cement ratio which is about 45 litre per bag cement for m10 grade of concrete. 1 bag cement required = 45 litre of water. 51 bags = 51×45= 2295 litre of water. So we have required water consumption in pcc 1:4:8 is approx 2295 litre of water for 100m2 having 150 mm thick slab.

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined.

Pozzolanic Portland cement (CEM type IP) is one such cement having an average of 30% fly ash blended to the cement in the manufacturing process. Fly ash is an effective and economical additive for cement. It reduces cement consumption of concrete of hardening of the concrete, allowing more time to dissipate the heat to the environment.

The production of 1 m³ of concrete requires 2,775 MJ of energy. This energy comes mostly from oil burning, which generates CO2. 2.775 MJ of energy is produced by 0.37 barrels of oil. Saving concrete, e.g. by adopting appropriate building solutions, means therefore not only reducing fossil fuels consumption, but also pollutant emissions.
