Effect of different types of water and cement mortars
Water is mixed with the cement powder to form a paste which holds the sand and/or aggregates together
Many builders use any water which is available easily on the site such as bore well water, water from the swamp etc. for mixing the cement mortars or concrete. However, water which is acidic owing to the pressure of uncombined carbon dioxide of organic or inorganic acids, is more aggressive in negative action, the degree and rate of attack increases as the acidity increases.
In general, acid solutions which attack cement mortar or concrete by dissolving part of the cement do not cause any expansion, but progressively weaken the materials by removal of cementing constituents forming soft and mushy mass. As a company, MAPOK Construction Limited, we don’t just use any water before checking, we also don’t use dirty rainwater, dirty water from the swamp, or seawater in cement mortars, concrete or reinforced concrete because it causes much lesser strength and corrosion to the reinforcement in concrete and cement mortars.
Some Seawater for example contains a small quantity of sodium and potassium salts. It is important to note that the large quantities of chlorides in the water causes efflorescence and dampness.
MAPOK Construction Limited seeks to meet the constant growing demands of clients in Uganda and elsewhere in East Africa with maximum flexibility, and with expert knowledge of engineering, economic and environmental issues of vital importance in the region
