The following nomenclature is normally given to a cement-lime mortar: X1:X2:X3 Where X1 = Units of volume of cement (portland or blended) X2 = Units of volume of … Generally, lime mortar mix ratio for brickwork ranges from 1:3 to 1:5 depending on the strength. (he quoted ($99 a yard plus $4 per mile from the plant in November 2010 in northern Nevada ) The specified minimum cement content, if applicable. It is important to note that the water to cement ratio determines the strength of the substance. For the cement, my current plan is to try 1:1:1 portland:snowcrete:NHL . A well-graded soil requires about 5% cement, whereas a poorly graded, uniform sand may require about 9% of cement. The proportions used in cement-lime mortars are determined by units of volume in the proportion specification in ASTM C270. Lime applies if you use Portland cement type) Water.
