Production method of low-viscosity high-strength concrete
The invention discloses a production method of low-viscosity and high-strength concrete. The low-viscosity and high-strength concrete comprises the following raw materials in parts by weight. The radiation-resistant cement is prepared from 30-50 parts of Portland cement clinker, 10-20 parts of carbon fibers, 15-25 parts of steel fibers, 35-45 parts of a mineral admixture, 30-40 parts of glass beads, 3-10 parts of a radiation absorbent, 10-30 parts of a gelatinizing agent, 40-80 parts of aggregate, 15-25 parts of a composite foaming agent, 5-25 parts of a high-efficiency water reducing agent and the balance of water. According to the production method of the low-viscosity high-strength concrete, the vitrified microbeads are arranged, the physical and chemical properties of the vitrified microbeads are very stable, and the aging resistance and weather resistance of the concrete can be effectively improved by using the vitrified microbeads; the problems that a polyphenyl granule organic material is inflammable and poor in fireproof performance are solved, the defects that harmful gas is generated at high temperature, aging resistance and weather resistance are low, and rebound performance is large in the construction process are overcome, the comprehensive performance and the construction performance of the concrete are improved and perfected, and the vitrified microbeads are good in fluidity and workability in the mortar stirring project and can be recycled. And thus, the viscosity of the concrete during mixing can be effectively reduced.
本发明公开了一种低粘度高强度混凝土的生产方法，包括以下重量份的原料；硅酸盐水泥熟料30‑50份，碳纤维10‑20份，钢纤维15‑25份，矿物掺合料35‑45份，玻化微珠30‑40份，辐射吸收剂3‑10份，糊化剂10‑30份，骨料40‑80份，复合发泡剂15‑25份，高效减水剂5‑25份，余量为水。该低粘度高强度混凝土的生产方法中设置有玻化微珠，玻化微珠的理化性能十分稳定，玻化微珠的使用能够有效提高混凝土的耐老化性和耐候性，弥补了聚苯颗粒有机材料易燃﹑防火性能差的问题﹑高温产生有害气体和耐老化耐候性低﹑施工中反弹性大等缺陷，提高并完善了混凝土的综合性能和施工性能，且玻化微珠在砂浆搅拌工程中流动性好，和易性佳，进而能够有效降低混凝土混合时的粘度。
