Field Test Of Mud Mortar
The soil should be ground to a fine powder and mixed with sufficient water, added in small quantities. The mix should then be kneaded into a plastic mass of the required consistency.
Take a handful of the soil prepared AND FORM A BALL OF ABOUT 80MM DIAMETER
Keep the ball in the sun for drying when dried, examine the ball for loss of shape and surface cracks, if any.
If the ball prepared has deformed on drying and crumbles easily when pressed lightly, it may be inferred that sand content is excessive.
If the ball is hard but shows cracks on the surface, then the sand content is insufficient.
If the soil is not found suitable, as inferred above, the test should be repeated after modifying the composition of the soil, such as by mixing different proportions of two soils or by addition of sand or clay whichever is needed, for checking the stability.
