塑性混凝土的研究

Study on Plastic Concrete

防渗墙采用塑性混凝土施工,应具有良好的可施工性,通过塑性混凝土配合比的设计,可以满足其施工要求。当固定膨润土的掺量、改变水泥用量时,塑性混凝土28 d的立方体抗压强度、轴心抗压强度、立方体劈裂抗拉强度、轴心抗拉强度、静力抗压弹性模量随着水泥用量的增加而增加;如果固定水泥掺量、改变膨润土的掺量时,结果却与其相反。

Using plastic concrete for impervious wall construction should have good constructability.Through the design of plastic concrete mix proportion,it can satisfy the construction requirements.When the quantity of bentonite is fixed and the dosage of cement is changed,the cubic compressive strength,prism compressive strength,cube tensile splitting strength,prism tensile strength and static compressive elastic modulus of 28 d plastic concrete increase as the dosage of cement increases;if the dosage of cement is fixed and the quantity of bentonite is changed,the result is just opposite to it.
