Development of Controlled Low Strength MaterialsUsing CKD

Cement Kiln Dust (CKD) is a voluminous co-generatedproduct of the cement manufacturing process. Thisbook presents the feasibility of incorporating CKD,from various sources, as a replacement for Portlandcement in the development of Controlled Low StrengthMaterials (CLSM) with acceptable properties.The findings show that with a little Portland cementand moderate volumes of CKD a good mix that easilysatisfies the requirements of CLSM can be developed.Suitable CLSM mixes can also be produced withoutPortland cement, using CKD alone. The latter mixesshowed reasonable fresh and hardened properties,however, increased shrinkage was observed.Sustainable development in the cement industry can beachieved by producing CLSM with moderate volumes ofCKD as it reduces the use of Portland cement andconsumes a co-generated product that has little or nocurrent use. This book should be useful to cementcompanies or anyone else in the construction industrythat is interested in a cost effective sustainable CLSM.

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.
