Machine-made sand high-performance concrete
The invention relates to a machine-made sand high-performance concrete. The concrete is prepared from, by weight, 11.50 to 16.00 parts of a mixture of cement and fly ash; 3.50 to 5.50 parts of slag powder; 30.80 to 34.80 parts of machine-made sand; 41.80 to 43.20 parts of broken stone; 0.15 to 0.25 part of an additive; and water added to 100 parts. By optimizing the proportion range of the cement, the fly ash, the slag powder, the machine-made sand and the broken stone, the strength of the concrete is associated with the weight ratio of the components so as to adapt to preparation of C40-C60 concrete, the comprehensive performance of the concrete is improved through the additive, the workability of the concrete is improved, the cost is reduced, and good universality and economical efficiency are achieved.
本发明涉及一种机制砂高性能混凝土，其由包含以下重量份的原料组成，水泥和粉煤灰的混合物11.50~16.00份；矿渣粉3.50~5.50份；机制砂30.80~34.80份；碎石41.80~43.20份；外加剂0.15~0.25份；加水至100份。本发明通过优化水泥、粉煤灰、矿渣粉、机制砂和碎石的配比范围，使得混凝土的强度与这些组分的重量比相关联，以适应C40‑C60混凝土的制备，并通过外加剂提升混凝土的综合性能，在提高混凝土和易性、降低成本的同时，具有较好的通用性和经济性。
