To produce high-quality concrete by batching plant mini, you need to invest raw materials with good quality. The raw material of produced concrete is composed of sand, stone, cement, mineral powder and so on. What are the quality regulations and standards for raw materials for concrete batching plants?

Cement is a hydraulic binder that plays a major role in concrete cementation. Common cement is commonly used in civil engineering. The concrete in concrete batching plant is not only selected according to the characteristics of various cements, but its amount is mainly determined according to the strength index. The strength of cement is reflected in the strength grade of cement. The strength grade of the cement is formed by the strength obtained from the mortar test piece after the compression test. The cement has been stored for more than 3 months must be re-examined. The strength of cement should be slightly higher than or equal to the strength of the concrete. When the strength of concrete is low, the admixture can be blended to save cement using. The maximum amount of cement in each cubic meter concrete should not exceed 550 kg. The water used in mini batching plant for sale meets national standards for the production of concrete. Other water sources have passed the inspection before they can be used. Admixtures is additional materials used to improve the concrete production process and concrete performance to meet specific needs. The added material plays an increasingly important role in the production and application of batching plant mini. The dosage of admixture is usually more than 5% of the amount of cement, and its fineness is the same as or thinner than cement.
