The invention is related to nanocement production methods by modifying portland cement, as well as to nanocement compositions. The nanocement production method involves a mechanochemical activation of dispersed grains of portland cement in the presence of polymeric modifier, with the sodium naphthalenesulfonate content of at least 60 wt %, mineral siliceous additive containing at least 30 wt ...
Concrete mix ratio of 1:3:3 – On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi. On mixing water with the three ingredients, a paste is formed that binds them together till the concrete mix gets hardened. The strength concrete is inversely proportional to the water/cement ...
It is shown that, with this level of integration, it is possible to avoid about 38% of the CO 2 emissions produced by the cement manufacturing process. Furthermore, an estimation of the additional cost of implementing the precalcination system in the cement plant shows that a competitive cost of about 12 per ton of CO 2 avoided can be achieved.

1) The Aerated concrete is a much lighter concrete and can float on water. It does not contain coarse aggregates. It is composed of cement, sand, high watercement ratio and aluminium powder. Just as we mix the aluminium powder in the cementsand slurry, the expansion in the volume can be observed. Within 5 minutes it expands by 30%.
