Abstract:
The effect of soaps added in small amounts as integral waterproofing to cement mortar and concrete is .to diminish the absorption of water by capillary action to a marked extent arid to lessen the permeability to water under pressure. The compressive strength is not materially affected provided the waterproofed product is kept damp continuously until it gains the requisite strength and provided the soap is not one which causes foaming in the concrete mixer with entrainment of air in the finished product. If concrete containing soaps is allowed to become dry before it has attained the desired strength, it will always remain weak because, being waterproofed, water will not be able to gain free access to the interior of the mass and continue the hardening process.
