本研究针对沥青油毡作拱仓屋面防水层及仓房墙壁、地坪防潮层存在的渗漏、污染、强度低等问题,用补偿收缩混凝土代替沥青油毡作防水、防潮层的防水、防潮及储粮效果进行了生产性试验。试验表明:防水防潮效果优于沥青油毡。而且,仓温、粮温比对照仓明显降低;墙壁及地坪的抗压强度可提高至214kg/cm~2以上;费用明显降低,屋面处理比沥青油毡作屋面防水层降低费用13％左右,比采用挂瓦改造节约费用58.5～76.4％;墙壁处理比沥青油毡砂灰墙壁减少费用70％;地坪处理比沥青油毡加干砖地坪节约费用23％,并可避免3.4—苯并蓖对储粮的污染。
In this paper, aiming at the problem that the asphalt felt is used as the waterproofing and moisture-proofing and grain storage of the moisture-proof layer and warehouse wall of the arch roof, the seepage, the pollution and the low strength of the moisture-proof layer in the floor, compensating shrinkage concrete instead of asphalt felt Effect of a productive test. Tests show that: waterproof moisture better than asphalt felt. Moreover, the temperature of the warehouse and the grain temperature were significantly lower than that of the control warehouse; the compressive strength of the wall and the floor can be increased to over 214kg / cm 2; the cost is obviously reduced; the roofing treatment reduces the cost of the roofing waterproof layer by about 13% Cost savings of 58.5-76.4% over wall tiles; 70% less for wall treatment than asphalt felt wall; 23% for floor coverings than asphalt felt plus dry tile flooring and 3.4- Storage of grain pollution.
