一种具有补强、内养护和补偿收缩功能的混凝土制备方法
摘要：
本发明公开了一种具有补强、内养护和补偿收缩功能的混凝土制备方法。该混凝土所用原料及其质量百分比如下：普通硅酸盐水泥8％～17.5％，机制砂28％～41％，石子39％～45％，硅灰0.75％～1.5％，矿粉2％～4％，减水剂0.3％～0.65％，内养护剂0.5％～1.5％，有机早强组分0.03％～0.05％，水5％～7％，该混凝土由上述原料经拌和、浇筑、养护而成的。本发明将内养护剂与有机早强组分混合而成特种内养护剂，所加特种内养护剂具备高吸水、高保水、可控释水的特性，为混凝土提供持续有效的早期内养护作用，降低混凝土早期收缩开裂的风险。
摘要（英）：

The invention discloses a preparation method of concrete with the functions of reinforcing, internal curing and shrinkage compensating. The concrete comprises the following raw materials: in percent by mass, 8-17.5% of ordinary Portland cement, 28-41% of machine-made sand, 39-45% of cobblestone, 0.75-1.5% of silica fume, 2-4% of mineral powder, 0.3-0.65% of a water reducing agent, 0.5-1.5% of an internal curing agent, 0.03-0.05% of an organic early strength component and 5-7% of water. The concrete is obtained through mixing, pouring and curing of the raw materials. A special internal curing agent is obtained through mixing of the internal curing agent and the organic early strength component, and the special internal curing agent has the characteristics of high water absorption, high water retention and controlled release water, and provides a continuous and effective early internal curing effect for the concrete, so that the risk of early shrinkage cracking of the concrete is reduced.
