对混凝土质量隐患的分析与预防（Analysis and prevention of concrete quality hidden danger）

对混凝土质量隐患的分析与预防（Analysis and prevention of concrete quality hidden danger） 1. concrete as one of the most widely used structural material, its quality is directly related to the construction quality, service life and peoples lives and property safety. Our country is in the infrastructure construction peak, if in the production process of quality and not enough, will bring a huge price. Concrete production supply is a continuous process, but the concrete is a kind of product can not immediately be confirmed whether the follow-up inspection work fully qualified and should immediately use product placement. In its production process is often affected by different factors, the variability of concrete quality will make the. Commercial concrete quality must be qualified strength, good durability and economy of concrete. The three is an organic whole, mutual influence, are indispensable. Trouble analysis and prevention of concrete production in 2. From the angle of concrete production, the quality should be controlled from the raw materials, formulation design, production control, delivery and other aspects, to ensure the concrete quality fully meet the design requirements. This often exists in several aspects influencing factors in most places. 2.1 concrete because of raw materials with quality problems due to quality defects 2.1.1 risk analysis The concrete engineering quality directly affects the overall quality of the reinforced concrete structure, concrete and the quality of raw materials and matching is appropriate also directly affects the quality of concrete engineering. Therefore, to ensure the quality of reinforced concrete structure is one of the important factors is to start from the concrete quality control of raw materials. Improper selection of raw materials will lead to concrete engineering quality defects or cracks, directly affect the quality of the whole project structure. The concrete quality defects or cracks produced due to improper selection of materi
