Application of collected dust stone powder in concrete as cementing material
The invention relates to a preparation method for concrete and particularly relates to application of collected dust stone powder in concrete and a preparation method for the concrete. According to the method, ingredients in parts by weight are proportioned as follows: in per cubic meter of concrete, the ratio of cement to slag powder to the collected dust stone powder is (17-33): (6-11): (0-10), or in per cubic meter of concrete, the ratio of the cement to the collected dust stone powder to pulverized coal ash is (17-33): (6-11): (10-6), or the concrete per cubic meter contains 17-33 parts by weight of cement, 0-11 parts by weight of slag powder, 17-0 part by weight of pulverized coal ash and 1-50 parts by weight of collected dust stone powder. Compared with the prior art, the application and the preparation method have the advantages that by replacing the pulverized coal ash or the slag powder with the collected dust stone powder, the large-scale utilization of the collected dust stone powder can be realized on the premise of meeting work performance and strength, so that not only is environmental protection facilitated, but also the production cost of the concrete is reduced.
