The need for air entrainment, says malisch, varies from region to region, running from 3% to 7% of the volume of the concrete. Skundrick notes that air entrainment additives can make a finish sticky, but the solutions to this lie with the finishing process, not with a change in mix design.

Numerous strategies have been advocated to reduce the potential for plastic shrinkage cracking in concrete through mixture proportioning, curing methods, or the use of fiber reinforcement. The effectiveness of each approach must be adequately quantified to determine whether the additional initial cost of each strategy is justified.
Specimens were removed from the molds at 1 day and kept in a water tank until the age of 28 days. Five specimens were tested under compression immediately after conditioning; these control specimens will be referred to as those tested after exposure to normal curing condition (unheated).

The uniformity of cement mixing piles is visually tested on the drilled core samples, significantly relying on experience and extremely inaccurate. The cement content of core samples is an important parameter to quantify the uniformity of cement mixing piles. However, there were no well-accepted methods of testing the cement content of core samples.

It is noted also that, the evolution of resistances in time is not the same for all the tested concretes. The ratio of the compressive strengths at 7 days compared to that of 28 days of the concretes with rubber aggregates is higher than that of the control concrete and this for the two tested formulations.
Further, the reaction with c 3 s and c 2 s was accelerated, thereby increasing the generation rates of ca(oh) 2 and c-s-h. The large amount of ca 2+ ions in these hydration products reacted with co 3 2− ions in co 2 nanobubble water, thereby increasing the generation of calcite-based caco 3 in the cement matrix.
