Self-compacting durable concrete and preparation method thereof
The invention discloses self-compacting concrete and a preparation method thereof.The self-compacting concrete is prepared from, by weight, 200-280 parts of cement, 90-110 parts of fly ash, 35-45 parts of mineral powder, 800-850 parts of fine aggregate, 800-850 parts of coarse aggregate, 6.2-10.4 parts of water reducing agent and 100-112 parts of water, the coarse aggregate is a composition of natural coarse aggregate and modified recycled coarse aggregate, and the modified recycled coarse aggregate is a mixture of modified recycled coarse aggregate and modified recycled coarse aggregate. The mass of the modified recycled coarse aggregate accounts for 10-30% of the total mass of the coarse aggregate, and the modified recycled coarse aggregate is obtained by soaking a recycled coarse aggregate in nano-silica sol and then performing carbonization treatment. The self-compacting concrete prepared by the invention not only has better compressive strength, but also has better durability and freeze-thaw resistance, and can be suitable for constructional engineering in various environments.
本申请公开了一种自密实混凝土及其制备方法，自密实混凝土按照重量份计，包括如下组分：200‑280份水泥、90‑110份粉煤灰、35‑45份矿粉、800‑850份细骨料、800‑850份粗骨料、6.2‑10.4份减水剂和100‑112份水，其中，粗骨料包括天然粗骨料和改性再生粗骨料的组合物，所述改性再生粗骨料的质量占粗骨料总质量的10‑30%，所述改性再生粗骨料由再生粗骨料经由纳米硅溶胶浸泡后再经过碳化处理得到。本申请制备的自密实混凝土除了具有较好的抗压强度以外，还同时具有较好的耐久性和抗冻融性，能适用于各种环境的建筑工程中。
