| Abstract: | Three shapes of concrete blocks are discu ss ed.The contraction distortion is considered to be the major phenominon in the st ructural distortion of concrete blocks,and considerations in the selection of ri ght block shapes are suggested.The authors further explore the causes of the dis tortion and cracking of walls of concrete hollow blocks and point out that,to pr event the distortion and cracking,technical measures should be taken such as the adequate filling in the horizontal joint,the right preparation of masonry morta r,and the arrangement of binding joints.They also give a brief account of the st ructural design procedures for the concrete hollow blocks. |
