哈尔滨市房地局砖厂,于1984年开始利用垃圾制砖的试验。1986年,这个厂进行了三次试制,共生产出28万块“垃圾砖”。这种砖的原料为50%粘土和50%经过陈腐的垃圾。由于垃圾具有一定的热值,不必再添加内燃料。试制的“垃圾砖”为标准砖。经测试,其抗压强度为113公斤/平方厘米,抗折强度为31公斤/平方厘米,均达到普通粘土砖的国家标准。砖的外观光亮,色泽明快。并具有自重较轻(1200～1300公斤/立方米),冻融损失小(0.56%),导热系数较低(0.418千卡/米·时·度)等优点,但吸水率稍高(27.33%)。使用的垃圾主要构成组分为:煤灰15%,铁制品1%,残土20%,菜叶、果皮20%,碎纸15%,包装塑料袋9%,玻璃制品5%,木 The Harbin Fangdi Bureau brick factory began to use the test of rubbish brick making in 1984. In 1986, the factory carried out three trial productions, producing a total of 280,000 “rubber bricks.” The raw material of this brick is 50% clay and 50% of old garbage. Since garbage has a certain calorific value, it is not necessary to add internal fuel. Trial bricks are standard bricks. After testing, its compressive strength is 113 kg/cm2, and its bending strength is 31 kg/cm2, all reaching the national standard for ordinary clay bricks. Bricks look bright and bright. And has a lighter weight (1200 ~ 1300 kg / m3), small freeze-thaw loss (0.56%), lower thermal conductivity (0.418 kcal / m · hour · degree) and other advantages, but slightly higher water absorption (27.33% ). The main components of waste used are: coal ash 15%, iron products 1%, residual soil 20%, leaves, peels 20%, shredded paper 15%, plastic bags 9%, glass products 5%, wood
