商品混凝土的应用技术

The application technology of ready-mixed concrete

商品混凝土省时、省力 ,方便快捷 ,是一种值得推广的半成品。而要预拌混凝土 ,则须掌握其质量控制要点 ,使其配合比设计满足四项基本要求 ,其原材料的性质及含量均要符合技术指标。阐述了混凝土拌合物的和易性是影响混凝土质量的主要因素 。

The ready mixed concrete is worthy of being popularized as a semi finished good because of saving time, saving labor and its conbenience. In the concrete premixing the quality controlling key points must be grasped to make the mix proportion to meet the four basic demands and the quality and content of raw materials must measure up to technical qualification. At the same time author point out that the workability of mixtures is main element influencing concrete's quality and reducing intensity standard deviation is an effective way to enhance benefit. Blending with water reducing agent is also a effective measure. At last other advantages and disadvantages are analyzed.
