摘要:为了提高混凝土的抗渗性能,以及减免由于混凝土收缩而产生的裂缝,在混凝土中经常加入膨胀剂。混凝土膨胀剂的功能是使硬化后的混凝土产生一定的体积膨胀,抵销混凝土硬化早期产生的体积收缩。
Abstract: To improve the impermeability of concrete,and reduce cracks in concrete created by the shrinkage,expansive agent is often added. Concrete expansion function is to produce a certain volume expansion after concrete hardening of concrete to eliminate concrete early hardening volume contraction.
