Masonry Mortar Types Masonry Mortar Types Masonry is held together with mortar (between pieces of masonry) and grout (fills cavities in the masonry unit). ... however, it is still sometimes used in historic preservation projects. It has the lowest compressive strength of any mortar so it will not cause damage to fragile stones or masonry.
Cement dosage, watercement ratio and size of the aggregates were kept constant as 400 kg/m 3 and for two types of concrete mixture. Thus we determined the effect of cement type on strength development of concrete.
This gives the concrete using this type of cement a threeday compressive strength equal to the sevenday compressive strength of types I and II. Its sevenday compressive strength is almost equal to 28day compressive strengths of types I and II.
