Studies on properties of Flowable Earth Mix concrete for monolithic load bearing walls

Abstract The paper presents the results of experimental studies carried out on the properties of Flowable Earth Mix (FEM) Concrete. The FEM concrete can be used for the construction of monolithic load bearing walls in buildings. Smaller structures such as sanitary units, soak pits, water storage tanks etc. can also be built with single casting. Compared to the formwork and compaction energy used in monolithic rammed earth wall constructions, casting FEM concrete requires simpler formwork (minimising the cost of formwork) and minimum compaction energy for casting. The properties of FEM Concrete such as workability, compressive strength, flexural strength, drying shrinkage and moisture movements are discussed. The variables considered included type of soil, clay content of the mix and cement content. The results indicate the feasibility of producing monolithic FEM Concrete walls for load bearing buildings. It is easy to achieve required workability and strength of FEM Concrete through the mix design.
