Sand should have good graded Wuchang build sand-lime brick, sand-lime brick porosity Wuchang Which is good, its reference graded as follows: 2.5 ~ 5.0mm particle content of 01.2 ~ 2.5mm 3% ~ 5% 0.3 ~ 1.2 mm 45% ~ 60% 0.15 ~ 0.3mm 20% ~ 30% <0.15 <30% ⑦ sands chloride content should not exceed 0.01% .⑧ sand mica content shall not exceed 0.5%. Production Practice has proved that the use of particles coarse sand and uniform particle size or particle size less than 0.075m special sand-lime brick sand Wuchang price, technical performance sand-lime brick made of all can not meet the requirements. In general, the fineness modulus of 2.2 to 1.6 gray sand bricks, sand and 1.5 to 0.7 extra fine sand, the best results. 1) for bulk material in front of lime and sand mix the ingredients must be crushing, grinding fineness of the production process to achieve the required general chunk of lime used jaw crusher for crushing. Needs to be crushed lime powder Grinding General grinding ball mill for lime (2) mix design mix sand-lime brick ① Mix ratio shall meet the following requirements a. physical and mechanical properties, especially compressive strength requirements. General compressive strength 10Mpa above requirements, and also to meet the frost, carbonation, acid, fire resistance, shrinkage and other performance requirements. b. to meet the brick molding of the plastic mix requirements. c. Mix to try to reduce costs and improve economic efficiency. Wuchang sand-lime brick prices _ _ East Lake sand-lime brick cement pavilion by pavilion Hongshan District of Wuhan cement operation.
