Access the Suitability of Local Soil and Demolishing Waste for Rammed Earth

Abstract

Rammed earth is an ancient building technique used in many regions of the world using natural raw materials such as earth, chalk, lime or gravel. It is a monolithic construction and the process involves compact the soil in progressive layers in a rigid formwork. The paper focusing on the use of locally available material which are not energy intensive. Also demolishing waste and flyash is used to replace the natural sand.

The properties of cement stabilized rammed earth was studied in terms of density and strength. The effect of varying percentage of demolishing waste, flyash and their effect to increase of unconfined compressive strength is studied. The rammed samples were made and stabilised with cement at fix percentages of cement as 8 %. Based on the results of this study and from the earlier investigations it is clear that the clay content predominantly in non swelling soil is an important parameter of rammed earth to improve bond strength. Also the presence of courser material such as gravel and sand is play an important role in strength gaining is noted.
