mortar texture Closely interlocking crystals of fine grain size, formed by the crushing and recrystallization of a rock that was originally coarser grained. It is a texture produced by shearing of the rock during dynamic metamorphism.

What is the consistency of mortar?

Mortar, however, is different from grout. The proportions of ingredients are somewhat variable, but mortar should always dry to a solid state that will not crumble to the touch. While “wet,” or during application, it should be generally the consistency of mashed potatoes — soft, but able to hold its shape.

What type of material is mortar?

Mortar consists of inert siliceous (sandy) material mixed with cement and water in such proportions that the resulting substance will be sufficiently plastic to enable ready application with the mason’s trowel and to flow slightly but not collapse under the weight of the masonry units.
