concrete incorporated cs-sr3 has good workability and high water-reducing rate, easy to construct when freshly mixed and yielding excellent mechanical performance after hardening.
the invention discloses a testing device of the volume compression coefficient of freshly mixed concrete under a side-limit condition and a testing method thereof.
本发明公开了一种侧限条件下新拌混凝土体积压缩系数的测试装置及其测试方法。
the surface of modified eps can be changed from the character of water-repellent to hydrophilic, and be wetted by freshly mixed portland cement paste.
