Masonry Materials

Concrete Block Curing and Block Types

Description

Concrete masonry units are made by mixing stiff concrete from Portland cement, aggregates, and water. The mix is placed into metal molds and vibrated so it settles evenly and does not separate. The wet blocks are then removed from the molds and set on racks.

After molding, the blocks are moved to...

制造混凝土砌块包括将由波特兰水泥、骨料和水组成的干硬性混凝土倒入金属模具中。

随后进行振荡,不久后将湿润的块体脱模至支架上。

然后将潮湿的砌块运送至蒸汽窑进行蒸汽养护,或运送至高压釜进行高压蒸汽养护。

砌块的标称尺寸通常标注为高8英寸、宽8英寸、长16英寸,但实际上每个砌块的尺寸略小于此数值。

在混凝土砌块的公称尺寸中,已包含施工接缝中使用的3/8英寸厚砂浆。

混凝土砌块主要分为三类:实心承重型、空心承重型和非承重型。其有多种形状和尺寸可供选择,例如顺砖砌块、单角砌块和A型砌块。

例如,A型砌块可用于建造需要在空心孔洞中灌注竖向钢筋的墙体,特别是在空间受限、难以将砌块穿过外露钢筋的情况下。
