屋面板制作的有效材料钢丝网水泥板

钢丝网水泥板是由水泥、砂子、水、外加剂经拌合、成形、养护而成的板材,钢筋、钢丝或钢丝网作为加筋材料提向板材的抗折强度和抗冲击性能。按用途分为屋面板和楼板两类:根据LBl6308—1996《钢处网水泥板》标淮,水泥应采用强度等级不低于32.5的普通硅酸盐水泥和矿渣硅酸盐水泥。钢骨架轻型板

Steel mesh cement board is composed of cement, sand, water and additive through mixing, forming and curing of plate, steel, steel wire or steel wire mesh as the reinforced material provided to the plate flexural strength and impact resistance. According to the purpose of the points for the roof and the floor: according to LBl6308 - 1996 the steel net cement board "standard, cement shall be not less than 32.5 ordinary portland cement and Portland slag cement with strength grade.

沙子宜采用细度模数为2.0一3.5的天然砂,最大粒径应不超过4mm,砂子含泥量应不大于2%,云母含量应不大于0.5%。拌含水应采用可饮淡水.严禁使用脏河水、海水、生活或工业废水。外加剂宜采用低引气型高效减水剂,也uf采用其他外加剂,不得掺用氯她作早强和防冻剂:钢筋、钢丝和钢丝网宜采用B级钢筋或冷拔低碳钢丝,构造筋应采用I级钢筋。钢丝网一般宜采用直径为0.9—1.0 mm,网格尺寸为10mmx10mm的冷拔低碳钢丝编织网,也可采用其他规格的钢丝网,但网丝直径不得大于2mm、,网格尺寸不得大于50mmx 50mm钢丝的抗拉强度不得低于450MPa。

Sand should adopt 2.0 3.5 natural sand fineness modulus, maximum particle size should be not more than 4mm, the mud sand amount should be less than 2%, the mica content should be no more than 0.5%. The mixture of water and water should be used to drink fresh water, and it is forbidden to use dirty water, seawater, life or industrial waste water.. Admixtures should adopt low air entraining superplasticizer, UF with other admixture, shall not be mixed with chlorine her early strength and antifreeze: steel, steel wire and wire mesh should be the grade B steel or cold drawn low carbon wire, structural reinforcement should adopts reinforced I level. Wire mesh is generally preferable to a diameter of 0.9 - 1.0 mm in diameter, mesh size 10mmx10mm of cold drawn low carbon steel wire braid and the other specifications of steel wire, but twine diameter not greater than 2mm, mesh size shall not greater than 50mmX 50mm steel wire tensile strength of not less than 450.
