Development of Controlled Low Strength Materials Using Ckd

Cement Kiln Dust (CKD) is a voluminous co-generated product of the cement manufacturing process. This book presents the feasibility of incorporating CKD, from various sources, as a replacement for Portland cement in the development of Controlled Low Strength Materials (CLSM) with acceptable properties. The findings show that with a little Portland cement and moderate volumes of CKD a good mix that easily satisfies the requirements of CLSM can be developed. Suitable CLSM mixes can also be produced without Portland cement, using CKD alone. The latter mixes showed reasonable fresh and hardened properties, however, increased shrinkage was observed. Sustainable development in the cement industry can be achieved by producing CLSM with moderate volumes of CKD as it reduces the use of Portland cement and consumes a co-generated product that has little or no current use. This book should be useful to cement companies or anyone else in the construction industry that is interested in a cost effective sustainable CLSM.
