塑性混凝土与普通混凝土不同之处在于它包含的材料种类多,胶凝材料成分复杂。各种胶凝材料成分对塑性混凝土性能影响各不一样。如胶凝材料中水泥对强度性能影响较大,当水泥用量增大时,强度虽然提高了,同时塑性混凝土的弹性模量亦增大,容易造成弹性模量指标满足不了要求。又如水胶比亦是塑性混凝土一个重要影响因素,同时水胶比又与塑性混凝土的工作性能息息相关。因此,塑性混凝土的配合比设计是一项极复杂的工作,为了配制出满足所要求性能的塑性混凝土,必须反复设计试配调试才能完成。
Plastic concrete and ordinary concrete is that it contains many types of materials, cementitious materials complex composition. Various cementitious materials have different effects on the performance of plastic concrete. Such as cementitious materials, cement on the strength of a greater impact on the performance, when the amount of cement increases, although the strength increased, while the plastic modulus of the plastic also increased, easily lead to elastic modulus index can not meet the requirements. Another example is the water-plastic ratio is also an important plasticity of concrete, at the same time, water-plastic ratio and plastic concrete performance is closely related. Therefore, the plastic concrete mix design is a very complex job, in order to formulate to meet the required performance of plastic concrete, you must repeatedly design commissioning to complete.
