The expansive experiment shows steel slag can compensate the concrete shrinkage during a long time and hybrid fiber restrains the concrete shrinkage 钢渣掺合料对混凝土收缩具有长期补偿作用,混杂纤维起到抑制混凝土收缩的作用。
Research about the effects of mineral admixture on the compressive strength and pore porosity of low - temperature concrete without antifreeze 摘要目的研究了在不掺防冻剂的情况下,掺合料种类及掺量对低温沉凝土强度及孔隙率的影响。
Mix mineral material can improve the concrete frost resistance ability , and the effect of compound mineral mixture surpassing solely mineral mixture 掺合料的掺入改善了混凝土抵抗冻融破坏的能力,且复合掺合料的效果优于单一掺合料。
In modern concrete technology , the mineral admixtures controlled by some indexes has become a prerequisite compose of high performance concrete 在现代混凝土技术中,经过一定质量控制的矿物掺合料已成为高性能混凝土不可或缺的组分之一。
Standard performance specification for coal tar pitch emulsion pavement sealer mix formulations containing mineral aggregates and optional polymeric admixtures 含矿物集料和附加聚合物掺合料的煤焦油沥青乳化液铺面密封料搅拌配方的标准性能规范
The way of producing the high performance concrete by using active mineral mixmaterial and the effective compound has been an important technical measure 采用活性矿物细掺合料与高效减水剂复合效应来配制高性能混凝土已成为当前混凝土技术的又一重要技术措施。
In 21 century , the path of concrete is green concrete , that is how to use each mineral admixture to improve the high performance and unpollution of concrete 21世纪的混凝土发展方向是绿色混凝土,其最大的特点就是通过大量的掺入各种矿物掺合料来实现其高性能化和环保性。
As the replacement material of cement and concrete , superfine slag powder is widely used for it can be employed to improve the strength of cement and the durability of concrete 矿渣微粉作为生产水泥的原料和混凝土的掺合料,可有效提高水泥的强度和改善混凝土的耐久性。
Compared with that of 10 years before , material designation has changed much and that mineral mixtures as main components are applied in concrete has also become more common 相比十年前混凝土的配合比设计理论已有了较大变化,矿物掺合料已成了配制hpc不可或缺的组分之一。
In order to reduce the cost and increase the rpc strength , the substitution of mixed minerals such as ultra - pulverized fly ash for silica fume quantity can be lower than 20 % 为降低成本而又不大幅度损害活性粉末混凝土的强度,超细粉煤灰等矿物掺合料替代硅灰的量不宜超过加20 % 。
