  • Properties of the mortar and the remitar admixed with waterproofer(CS) which was made from cement-sludge were compared with those of the other waterproofers (DA, DD and DH). 1. The CS waterproofer appeared to have a good waterproofness(compressive strength-79%, water absorption ratio-60%, waterpermeability ratio-70%)in cement mortar. 2. The CS waterproofer appeared to have an excellent watertightness(compressive strength-125% water absorption ratio-45%, water permeability ratio-60%) in remitar.

  • Utilization of underground construction if increased by the large size & skycraperlization of building recently. Therefore. waterproof dependence of underground construction is risen. However, water leakage was happened by rupture by concrete conduct, drying shrinkage. form tie. In underground environment soil class, degradation of waterproofing is showing to corrode by oil. An odious smell by oil, promotion evil of reinforcing rod corrosion, declination of durability can happen. Then, practical un degree of underground spare becomes low, Because oil or water permeates by construction by degradation to waterproof class corrode by oil, is considered to affect evil durability of construction.
