THE EFFECT OF REVERSE FLOTATION METHOD ON SILICA SAND AS WATERPROOFING MORTAR

THE EFFECT OF REVERSE FLOTATION METHOD ON SILICA SAND AS WATERPROOFING MORTAR. Waterproof fabrication mortar cement by silica sand using reverse flotation (RFS) method was evaluated waterproof absorption coefficient, compressive strength test, attractive and contact angle. RFS is used to replace agent aggregate reduce cost. The aims of this experiment are know the process, ratio between with mortar, determine performance characteristic cement. Methods prepared RFS, fabrication, testing (compressive strength, tensile permeability, angle, XRF, FTIR, SEM, BET). Variable cement/silica sand, concentrations CaCl2, curing time, oleic acid, sodium oleate addition. Optimum collector addition obtained acid compress 167.65 kg/cm2, 0.16 MPa, permeability 4.6 cm, angle 95°. Curing inside water effect outside temperature give kg/cm2 163.24 cm 12 cm. CaCl2 gained at 1.8M 64.29 0.15 2.4 cement/RFS 1:1 950.
