A small team of materials scientists and environmental engineers at Imperial College London has found that using olivine in cement could result in carbon-negative concrete. In their study, published in the journal Royal Society Open Science, the group conducted experiments with cement mixing that resulted in a way to produce it in a …
In a mixing container, add no more than 1 part cement to 2 parts sand. For some applications, you may add up to a 1:8 ratio of cement to sand. More cement means more strength and stickiness but less workability. Ratios with more cement than a 1:2 ratio with sand will prove difficult to work with and some of the aggregate may not bind correctly.
