What equipment or method is ideal for placing concrete in vertical forms or dams? O Conveyor belts O Mobile batcher mixers O Ready Mix trucks O BucketsGiven a Fineness Modulus of 2.8 and a nominal aggregate size of 1 inch to construct a 1.5x3 x200"grade wall, provide a "ball-park" estimate for the bulk volume percent of fine aggregate and cement for a 1:2:3 mix design. Secondly, provide an actual esitmate for volume of the coarse aggregate. 67%, about 600 cubic feet 33% , about 22 cubic yards 71%, about 22 cubic feet 29% , about 600 cubic yardsYou are to be pouring a 5-inch thick, 100' x 50' commercial building slab, 5" . If you used a M25 mix design, how much cement and aggregate would you need? Assume a void ratio of 54% for the coarse and fine aggregate. about 500 and 1000 cubic feet of cement and aggregate, respectively. about 600 and 1200 cubic feet of cement and aggregate, respectively. about 800 and 1600 cubic feet of cement and aggregate, respectively. about 1000 and 2000 cubic feet of cement and aggregate, respectively.What concrete properties should be monitored, managed, or maintained during curing? humidity and temperature segregation O surface roughness workabilityIn general, what curing methods works best for curing concrete? O Covering concrete with membrane forming Fogging and sprinkling O Wet coverings O Supplying heat and additional moisture to the concreteWhat cooling methods is more efficient for hot weather concreting? O Adding ice to the mixing water O Cooling aggregates O Reduce the rate of evaporation by using wind screens O Use liquid nitrogen to cool the concrete
