| Abstract: | The application of high-performance polycarboxylate superlasticizer in constructing flowing and high strength manufactured sand concrete and the optimization of concrete mix proportions can dramatically reduce the construction cost and increase the benefit of each cube concrete. The pre-pared C30, C40, C50 flowing and high strength manufactured sand concrete, compared with concrete with FDN Superplasticizer Added, achieve the goal of cost reduction. |
