广东省东莞县建筑材料厂日产红砖5万块。在生产过程中,每天约有5～6吨碎砖,以往都当废料扔掉。该厂广大职工积极开展综合利用工作后,将碎砖磨成粉,并利用石灰为胶结科,用当地河砂为骨科,配制成硅酸盐混合料,用自制的冲压式成型机(见右图)成型,试生产了小型空心砌块。原材料配合比为:废砖粉20%,石灰5%,河沙75%。砌块的孔洞率为40%,经蒸养后抗压强度达100公斤/厘米~2。
Guangdong Dongguan County Building Material Factory produces 50,000 red bricks per day. In the production process, there are about 5 to 6 tons of broken bricks every day. In the past, the scrap was thrown away. After the employees of the plant actively carried out comprehensive utilization work, the broken bricks were ground into powder, lime was used for cementation, local river sands were used for orthopedics, and silicate mixes were made. Self-made stamping molding machines were used (see right Figure) Molding, trial production of small hollow blocks. The ratio of raw materials is: 20% of brick waste, 5% of lime, and 75% of river sand. The porosity of the block is 40%, and the compressive strength after steaming is 100 kg/cm~2.
