| Research Abstract |
We made it clear following from this study.
1) We made it clear followings about the property of Limestone Crusher Sand and Stone containing Completely Recyclable Concrete.
・In case of increasing Powder volume per unit of concrete, the water content per unit volume of concrete increased a little. And the water content per unit of Limestone Aggregates Concrete became small as the one of Normal Concrete.
・In case of increasing Powder 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 bleeding on some ranges of water cement ratio increased not as for powder volume of Limestone Crusher Sand.
・The setting time of concrete on some ranges of water cement ratio doesn't have effects on powder volume.
2) We made it clear followings about the property of Limestone Aggregates Concrete.
・The Strength Performance of Limestone Aggregates Concrete is as same as the ones of Normal Concrete in case that water cement ratio is 40%, and became a little big in case that water cement ratio is 50,60%.
・The Fire Resistance of Limestone Aggregates Concrete is a little bad as Normal Aggregate Concrete about the down-rate of Compression strength of Concrete, but almost properties of both Concrete areequal.
