填充墙砌体工程规范(国外英文资料) Fill wall masonry engineering specification 9? Fill the wall masonry work ? 9.1?? General provisions? 9.1.1?? This chapter applies to building adopts hollow bricks, autoclaved aerated concrete block, lightweight aggregate concrete small hollow block masonry infilled wall masonry construction quality acceptance. ? 9.1.2?? It should be more than 28d during the period of the steam and gas concrete blocks and small hollow concrete blocks. ? Description: 9.1.2 aerated concrete block, lightweight aggregate concrete small block of cement gel enhanced piece of material, on the basis of the 28 d strength design intensity, and age to 28 d before their shrinking rapidly. In order to effectively control the cracks in the masonry and ensure the strength of the masonry, the period of the masonry was specified. ? 9.1.3?? It is strictly forbidden to throw and dump the hollow bricks, steamed concrete blocks and small hollow blocks of concrete. After the approach, should be piled up in neat and orderly, the height should not exceed 2m. Gas concrete blocks should be protected against rain. ? Explanation: 9.1.3? Considering the low strength of hollow bricks, gas concrete blocks and light aggregate concrete blocks, the collision is fragile, the moisture absorption is relatively large, and the special measures are made. ? 9.1.4?? Fill up the block of the wall masonry, and water the material in 2d. When steam and gas concrete block masonry, water should be watered in the right amount. ? Note: 9.1.4 block masonry is watered to make it more cohesive to the masonry. According to the water and water content of the water and water quality of the small bricks of hollow bricks and light aggregate concrete, the water content of the suitable water content is 10% to 15% respectively. Light aggregate concrete blocks should be 5 to 8 percent. Aerated concrete block out of the kettle when the moisture content of about 35%, after block gradually dry, the moisture content of construct
