DEDICATION

I would like to dedicate this work to my guardians, Mr. Sylifano N. Tindi and Mrs. Nelly N. Nambuchi, who have encouraged me throughout my education life. Without them I would not be where I am and also I would not be who I am.

ACKNOWLEDGEMENT

First and foremost, I wish to offer my greatest gratitude to the Lord God Almighty for having kept me alive and healthy throughout the college life. He has been the solemn protector and provider whenever I have needed him.

I wish to start by thanking the Masinde Muliro University of Science and Technology and particularly Civil and Structural Engineering department for taking me through the civil and structural engineering program up to the level I have reached. I wish to appreciate for what all the lecturers in and outside the department have instilled in me to be the person I am.

I also wish to extend my gratitude to my colleagues and close friends for their participation in this work. They have really helped me and therefore deserve my appreciation.

I also wish to appreciate my guardians for the parental care, social, moral, material and economic support they offered me.

ABSTRACT

Construction and Demolition (C & D) wastes constitute a major portion of total solid wastes production in the world, and most of them are disposed in landfills. Preservation of the environment and conservation of the rapidly diminishing natural resources should be the essence of sustainable development. As such, recycled aggregates are advocated. This report examines the possibilities of using fired clay products as coarse aggregates for the manufacturing of new concrete block. The coarse aggregates will be replaced with 20 -100% of crushed fired clay products. This should open a new avenue for building and construction industries to have an alternative construction material in future. Clay waste products chips when crushed to the required nominal sizes such as 10mm, 14mm, 20mm, 40mm etc provide a rough and irregular surface which aids in bonding of cement paste and the aggregate. Therefore the bond strength of concrete is likely to be increased when these aggregates are used. Careful consideration of the water absorption of clay based aggregates will be taken in the mix design to ensure that the workability of the mix is achieved. This project tries to encourage the recovery of waste materials to be used in production of aggregates for concrete hence conserving the environment.
