Pedestal grouting cement grouting material bearing cement-based grouting materials and grouting cracks prevention measures pedestal grouting and cement grouting material for irrigation is not correct, may make the casting after grouting material cracks, we summarizes some brief in long-term construction of grouting material crack prevention measures. 1, at the bottom of the slab crack width with 20 - commonly 40 mm advisable, more than 40 mm to be seam along the plate direction and long steel, jingmen grouting LiaoChang set in many families, the planners in the layout planning did not consider the heating tube parts cast-in-situ be reserved pipe hole, according to the size of net thickness of plate planning, precast slab results according to the drawing device tend to die or to form the gap is too small. Construction personnel in when the blue prints. the design, pay special attention to prompt planners, demand a change, to ensure that meet the plate width. 2 wire tube along the joints installation, general planning, which requires the construction personnel during filling and joints, it is important to note that works wire hanging wires to central plate joint space, to ensure that the wire at the bottom of the pipe concrete grouting material to enter and make the vibrating compaction. 3, sealing with fine stone gravel size should be strictly controlled in 5 - 15 mm, water cement ratio of 0. 44 - 0. 47, using ordinary Portland cement, concrete is poured machinery. Avoid by all means use sand instead of gravel mixing fine stone. 4, sealing with fine stone strength grade should not be lower than c20, and will be graded according to the requirements of planning, seam lien specimen plate mold before, carefully in the plate seam to rubbish, such as floor brick bat, ash and debris. Again before casting for wood chips and other sundry, water and rinse, then pouring plate seam. 5, in order to ensure the joints in the concrete pouring panyu high-strength non-shrink grout material manufacturer pulp before arrival planning strength grade, not plate seam cracking caused by the construction load, adopted a sit plasma device, the construction unit in no hurry to infuse stitch, and joints with the cement bag rolls into rod stuffing, do temporary processing. Above is bearing cement-based grouting materials and grouting cracks prevention measures luming grouting material prices briefly, expect to have help to you.
