以水玻璃为胶结料的耐酸胶泥、耐酸砂浆和耐酸混凝土,按《建筑防腐蚀工程施工及验收规范》(TJ212—76)第56条的要求:模数为2.6～2.8,比重则分别为1.40～1.45,1.40～1.42和1.38～1.40。当水玻璃模数或比重不符合上述要求,且无特殊情况时,必须遵循规范(TJ212—76,下同)附录四规定的方法进行调整。应当肯定,规范附录四所列的调整方法,总的来说是简便易行的,但并不完善。施工现场经常遇到成批水玻璃的模数低于规范要求的情况,无法按照附录四给定的方法进行调整,而必须采取掺加硅胶的方法。这
Acid-resisting clay, acid-resisting mortar and acid-proof concrete with water glass as cementing material are in accordance with the requirements of Article 56 of the “Code for Construction and Acceptance of Building Anti-corrosion Engineering” (TJ212-76): the modulus is 2.6 to 2.8, and the specific gravity is 1.40 respectively. ~1.45, 1.40 to 1.42, and 1.38 to 1.40. When the modulus or specific gravity of water glass does not meet the above requirements and there are no special circumstances, it must be adjusted according to the methods specified in Appendix IV of the specification (TJ212-76, the same below). It should be affirmed that the adjustment methods listed in Appendix 4 of the Code are, in general, simple, but not perfect. The construction site often encounters a situation where the modulus of the batch of water glass is lower than the specification, and cannot be adjusted in accordance with the method given in Appendix IV, but the method of adding silica gel must be adopted.
