Ground limestone powder full-manufactured sand high-strength recycled self-compacting concrete and application thereof
The invention discloses ground limestone powder full-manufactured sand high-strength recycled self-compacting concrete and application thereof. Per cubic meter of concrete contains 360-402kg of cement, 39-85kg of mineral powder, 45-88kg of fly ash, 70-96kg of ground limestone powder, 730-810kg of manufactured sand, 460-640kg of natural coarse aggregate, 300-400kg of recycled coarse aggregate, 10.3-13.7kg of polycarboxylate superplasticizer and 160-176kg of water. According to the full-manufactured sand high-strength recycled aggregate self-compacting concrete prepared from three additives including the ground limestone powder, the fly ash and the mineral powder, the fine aggregate is totally manufactured sand, and 31-46% of recycled coarse aggregate is added to the coarse aggregate, so that an effective path is provided for reducing exploitation and utilization of natural sand and sufficiently recycling concrete wastes, and a technical reference is provided for preparing the ground limestone powder full-manufactured sand self-compacting concrete.
