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...

制造混凝土砌体单元涉及将硬质混凝土(包括波特兰水泥、骨料和水)倒入金属模具中。
然后是振动,不久之后,湿块被脱模到机架上。
然后,湿块被运送到蒸汽窑进行蒸汽固化或高压蒸汽釜进行高压蒸汽固化。
块的标称尺寸通常列为高和宽 8 英寸,长度为 16 英寸,但实际上,每个块的尺寸略小。
用于施工缝的八分之三英寸厚的砂浆包含在混凝土砌块的标称尺寸中。
混凝土砌体单元分为三大类:实心承重、空心承重和非承重。有多种形状和尺寸可供选择,如担架单元、单角单元和 A 块单元。
例如,A 型块用于建造需要在空心内灌浆垂直钢筋的墙体,特别是在空间有限的情况下,砌块可以通过突出的钢筋。
混凝土砌块也根据其密度分为正...
