Preparation method of concrete mixed with dust collection stone powder and mineral powder based on strength and chloride ion permeation resistance double indexes
The invention relates to a preparation method of concrete, in particular to a preparation method of concrete compounded with dust collection stone powder and mineral powder based on double indexes of strength and chloride ion permeation resistance, and the concrete is prepared from the following components in parts by weight: 240 parts of cement, 0-100 parts of mineral powder, 0-30 parts of limestone powder, 130-150 parts of water, 500-1000 parts of sand, 800-1200 parts of pebbles, 3-10 parts of a water reducing agent and 3-10 parts of a reinforcing agent. Compared with the prior art, the method has the advantages that the problem that the water absorption rate of the dust collection stone powder is high can be solved, meanwhile, the dust collection stone powder is used for replacing the mineral powder, large-scale utilization of the dust collection stone powder can be achieved on the premise that the working performance and the strength are met, the production cost is reduced, and the production efficiency is improved. Environmental protection is facilitated, and the production cost of the concrete is reduced.
本发明涉及混凝土的制备方法，具体是一种基于强度和抗氯离子渗透双指标复掺收尘石粉‑矿粉混凝土的制备方法，按如下组分及重量份进行配比，水泥240份、矿粉0‑100份、石灰石粉0‑30份、水130‑150份、砂500‑1000份、石子800‑1200份、减水剂3‑10份以及增强剂3‑10份，经初次预混搅拌、二次搅拌、装模养护得到复掺收尘石粉‑矿粉混凝土，与现有技术相比，本发明能够克服收尘石粉吸水率高的问题，同时利用收尘石粉代替矿粉，能够在满足工作性能及强度的前提下，实现收尘石粉的规模化利用，不仅利于环保，而且降低了混凝土的生产成本。
