Generally referred to as 1:3 cement mortar is used with 1 volume of cement and 3 volume of sand, actually ignore the composition of water, generally in the proportion of about 0.6, that is, should be 1:3:0.6, the density of cement mortar is 2000Kg/ M3.
Note: The mortar used in the construction process is generally site-stirred for the convenience of construction. The cement mortar has a 1:3 ratio by weight ratio, and then is converted to a volume ratio according to the capacity of the in-situ mixer or material container; it is used in the construction of the structure. Mortar used more finished mortar, more with mortar strength, such as M5, M7.5, M10 mortar.
