Abstract
The present study investigates the compressive strength of cement-stabilized earth block masonry prisms with a number of masonry units and joint layer mortar combinations. The compressive strength of masonry was determined to be performed by uniaxial tests on 144 masonry prisms. The simple relationship has been identified for obtaining the compressive strength of stabilized earth block masonry from their corresponding block and mortar compressive strength. The predicted compressive strength of masonry prisms using the proposed expression is compared with 14 empirical equations and experimental data of past research available in the published literature. The compressive strength predicted by the expression proposed in the present study was found to be in good agreement with corresponding experimental data compared with other empirical equations available in the published literature.
Highlights
Available masonry units made with different materials and various manufacturing processes are being used for masonry construction
In the last couple of decades, there has been a focus on the use of cement-stabilized earth blocks as low-cost housing construction in developing countries [1]
In recent times, there has been an attention to the use of stabilized earth block masonry for construction of low story building due to the scarcity of river sand
Summary
Available masonry units made with different materials and various manufacturing processes are being used for masonry construction. Kaushik et al [11] conducted the tests to determine the uniaxial monotonic compressive stress-strain behavior and other characteristics of local hand molded burnt clay solid bricks, mortar, and unreinforced masonry prisms. Various blended mortars produced by 0, 10, 20, 30, and 40% replacement of sand with a clay brick waste were used Based on their analytical model, each researcher proposed the empirical formulas for the prediction of the compressive strength of masonry. Is emphasizes the requirement of conducting tests on the compressive behavior of stabilized earth block masonry and further developing a simple expression to determine the masonry compressive strength in function of the compressive strength of stabilized earth block and mortar The experimental data were only compared with prediction equation recommended by Eurocode. is emphasizes the requirement of conducting tests on the compressive behavior of stabilized earth block masonry and further developing a simple expression to determine the masonry compressive strength in function of the compressive strength of stabilized earth block and mortar
