Methods to Test the Compressive Strength of Earth Blocks

2021-8-27  The efficient design of new earth structures and the restoration of old structures both require a reliable assessment of the compressive strength of earth materials. However, there is still much debate on the best method to accurately measure the compressive strength of earth blocks. To solve the problem of measuring the compressive strength of the earth block, the

A Model for Testing Compressive and Flexural Strength

It has generally been established that, compressive strength and flexural strength are the common criteria for determining quality of compressed earth blocks. [11] Reports that quality control strength testing of compressed earth blocks has often followed procedures developed for fired clay and concrete block units [12]. However,

EFFECT OF HAND COMPACTION ON COMPRESSIVE

2015-4-13  The dry compressive strength of the blocks was determined according to BS 1881 part 116, 1983, employing a Universal Testing Machine (UTM). During the compressive test, each block of nominal dimension 290 x 140 x 120 mm was weighed and aligned on the UTM, followed by gradual application of load until failure. Maximum applied load was recorded
