Low-elastic-modulus light-weight high-strength concrete and preparation method thereof
The invention discloses low-elastic-modulus light-weight high-strength concrete, and relates to the technical field of building materials, and the concrete comprises the following raw materials by mass: 480-600kg/m < 3 > of cement; coal ash: 240-300 kg/m < 3 >; 80-100 kg/m < 3 > of silica fume; hollow glass beads: 64-80 kg/m < 3 >; pottery sand: 150-220 kg/m < 3 >; modified rubber particles: 120-180 kg/m < 3 >; ceramsite: 225-330 kg/m < 3 >; 2.4-3.0 kg/m < 3 > of a water reducing agent; and 1.6-2.0 kg/m < 3 > of a defoaming agent. The invention further provides a preparation method of the concrete, the problem of weak bonding of an interface transition area formed by rubber and a cement-based material is solved by adopting a method of wrapping the rubber particles with the quick-hardening sulphoaluminate cement, the problem that the rubber is easy to peel off under the load effect is solved, and the mechanical property of the rubber lightweight aggregate concrete is guaranteed.
本发明公开了一种低弹模轻质高强混凝土，涉及建筑材料技术领域，所述混凝土包括以下质量配比的原料：水泥：480～600kg/m3；粉煤灰：240～300kg/m3；硅灰：80～100kg/m3；空心玻璃微珠：64～80kg/m3；陶砂：150～220kg/m3；改性橡胶颗粒：120～180kg/m3；陶粒：225～330kg/m3；减水剂：2.4～3.0kg/m3；消泡剂：1.6～2.0kg/m3。本发明还提供了所述混凝土的制备方法，采用橡胶颗粒外面包裹快硬硫铝酸盐水泥的方法解决橡胶与水泥基材料形成的界面过渡区粘结薄弱问题，解决了荷载作用下橡胶易剥落的问题，保障了橡胶轻集料混凝土的力学性能。
