THE RESEACH OF COMPLETELY RECYCLABLE CONCRETE

1) We made it clear following from this study.1) We made it clear followings about the property ofLimestone Crusher Sand and Stone containing Completely Recyclable Concrete. In case of increasingPowder volume per unit of concrete，水content per unit volume of concrete increased a little. And the水content per unit ofLimestone Aggregates Concrete became small as the one of Normal Concrete. In case of increasingPowder volume per unit of concrete in condition of fixed Water volume，Air volume per unit of Concrete became small not as for water cement ratio. The volume of bleedingon some ranges of water cement ratio increased not as for powder volume of Limestone CrusherThe setting time of concrete on some ranges of water cement ratio doesn't have effects onpowder volume.2) We made it clear followings about the property of Limestone AggregatesConcrete. The Strength Performance of Limestone Aggregates Concrete is same as The ones of NormalConcrete in case that water cement ratio is 40%，因为a little big in case that water cement ratio is 50,60%. The Fire Resistance of LimestoneAggregates Concrete is a little bad as Normal Aggregate Concrete about the down-rate of CompressionConcrete strength, but almost properties of both Concrete areequal。
