Properties:

The given below are the properties of gunite :

(a) Gunite is better than conventional concrete.

(b) Gunite needs low water-cement ratio which is lower than for most concrete mixes.

(c) Gunite is structurally durable and adequate material.

(d) It is capable of fine bond along with masonry, concrete and steel.

(e) The drying shrinkage of gunite is somewhat higher than for most low slump conventional concrete and generally falls within the range of 0.06 to 0.10 %. Low slump conventional concrete is placed in heavier sections using larger aggregates and leaner mixes. It will tend to provide more shrinkage cracking and, therefore, may require a closer joint spacing.
