A maturity approach to estimate compressive strength ...

2018-1-1  The experimental results showed that the compressive strength or maturity of the carbonated concrete blocks was affected by two factors: accelerated cement hydration and carbonation extent. A high CO2 concentration, a fast gas flow rate and a moderate relative humidity were essential for enhancing the maturity and the strength development.

2020-4-30  The variation of compressive strength of the blocks with the quantity of additive has been plotted in Fig.4. It is observed that the compressive strength of the blocks varies in a non-linear pattern with the quantity of additive. Initially the compressive strength increases until a peak value is attained and decreases thereafter. The maximum compressive strength has been found to be 36 MPa for the value

In the case of 9 inches block the compressive strength is 2.59 N/mm2 and 3.94 N/mm2 for ages 7 days and 28 days respectively. This shows that there is a variation in compressive strength between the two blocks. To this end, it can be deduced that the strength of 9 inches block is more and higher than that of the 6 inches block.
