摘要:
试验是以工业废渣作为粗细骨料进行再生混凝土多孔砖配合比的研究.通过正交试验选定配合比,用振动挤压成型的方法制作A、B、C三类再生混凝土KP1型多孔砖,并按照<砌墙砖试验方法>(GB/T 2542-2003)规定的方法,分别对其进行抗压强度、收缩性能和冻融循环试验.试验研究结果依照<混凝土多孔砖>(JC 943-2004)进行评定,结果表明:A类的强度等级可达MU15,B、C类的可达到MU10;多孔砖的收缩性能较小,冻融循环试验结果符合要求,价格较低,可作为黏土砖的替代品用于砌体结构房屋.
Abstract:
The test was to study the mix ratio of recycled concrete porous bricks by using industrial waste residue as coarse and fine aggregate. The KP1 perforated bricks of reclaimed concrete of A, B and C were made by vibration extrusion molding by orthogonal test, and the compressive strength, shrinkage performance and freeze-thaw cycle tests were carried out according to the method specified in the test method > of < wall bricks (GB/T 2542-2003). The results of the test were evaluated according to the > of < concrete porous bricks (JC 943-2004), and the results showed that the strength grade of class A could reach MU15, and the strength grade of class B and C could reach MU10. The shrinkage performance of perforated bricks is small, the freeze-thaw cycle test results meet the requirements, and the price is low, which can be used as an alternative to clay bricks for masonry structure houses.
