item used in concrete highway wearing surfaces, sand (natural or manufactured) must contain at least 25.0% acid-insoluble residue in the plus 600 µm size fraction and in the minus 600 µm size fraction.
concrete. if all fine aggregate (sand) is used to make a one cubic metre batch, a large amount of cement-water paste is needed to coat and bond the particles. by adding coarse aggregate to the batch instead of a portion of the sand, the mixing water demand can be kept lower.
proportioning of cement, sand and coarse aggregate shall be 1:2:4 or as specified. coarse aggregate and sand shall be measured by measuring box of 30cmx30cmx38cm of suitable size equivalent to one bag cement of 1/30 m 3 or 0.035 m 3. cement shall be measured by bag weighing 50kg. sand shall be measured on the basis of its dry volume.
sand can be expected to contribute about 2 to 6 percent free moisture by weight, and gravel or stone about 1 or 2 percent. under average conditions that means that 104 pounds of sand would give you the equivalent of 100 pounds of sand in what is called a saturated surface dry (ssd) condition and 4 pounds (1/2 gallon) of free moisture.
these components are rarely found in one type of raw material; therefore, for the cement production the raw mix is selected for the following components: carbonate component (rich in calx) is contained in the raw mix in a quantity of 76-80%: limestone. mohs hardness is 1.8-3.0.
non-hydraulic cement. the non-hydraulic cement doesn't require water to get harden. it gets with the help of carbon dioxide (co 2) from the air. this type of cement needs dry conditions to harden. lime, gypsum plasters, and oxychloride are the required raw material to produce non-hydraulic cement. example: slaked lime is a non-hydraulic cement.
chemical properties of cement. the raw materials for cement production are limestone (calcium), sand or clay (silicon), bauxite (aluminum) and iron ore, and may include shells, chalk, marl, shale, clay, blast furnace slag, slate. chemical analysis of cement raw materials provides insight into the chemical properties of cement.
