Concrete compressive strength test

① In the same rubber powder particle size in the case of concrete slump, apparent density, 28d compressive strength Stationary conacrete plant with the increase of rubber powder content  decreased, while the gas content with the rubber powder content increases;
② In the case of the same rubber concrete mixer machine, the slump of  the concrete mixture, apparent density, and coagulation 28d compressive strength of soil with rubber powder and reduce the particle size decreases, the gas content increases with decreasing particle size
