Qingzhou peng shun machinery welcome you! Our company is the national building materials industry mechanization fixed-point production factory, the main products are cement tube machine, cement pole complete sets of equipment, gantry crane, etc.Temperature, humidity and volume change caused by external load is usually part of the reversible or completely reversible, however, because of the inappropriate material or solid chemical and mechanical effect caused by the volume change is irreversible, and, if continued, will accumulate volume change. Cement tube machine use the concrete using the characteristics of cement pipe production, better use of the cement concrete. Due to the dosage of mixed material varieties, properties and different, such as concrete cement pipe mechanical workability and admixture adaptability is not the same. So Yi Bi water, large fluidity loss of mixed material with good water retention, fluidity loss is smaller using mixed material collocation, can make up for each other, to prevent bleeding and segregation. Improve the workability of concrete as well as the adaptability and admixture. Such as copper slag, steel slag, slag and fly ash, coal gangue collocation is used. Can obtain better effect, use limestone as mixed material, can stimulate the cement early strength. The use of fly ash, slag in mixed material, not only can reduce the hydration heat of concrete. If join for the superfine powder, also can greatly improve the cement strength, lower ratio of clinker. When using cement pipe machinery building construction, do not blindly pursue early strength. After demoulding tubes should check the appearance quality, appearance defective tubes should be timely repair. Repair pipe solidification strength is not lower than the concrete strength, generally USES epoxy resin emulsion slurry or building adhesive, after handling damage repair base, then mixed cement and white powder, make the color close to the nature of concrete. Repairing adhesive after solidification, sand paper tools such as grinding flat surface.
