The use of rice husk ash in the construction industry offers many advantages both economically
and environmentally. Economically, the use of rice husk ash will reduce construction costs since
it is easily available and minimal costs are incurred in its production. Environmentally, its use
will reduce the demand for cement therefore slowing down the manufacture cement which has
proved to be hazardous to the environment.

The negative effects of climate change are becoming more and more of a threat to urban areas
globally. Changing precipitation patterns, an increase in the frequency of extreme weather
events, and rising temperatures are making it difficult to maintain current stormwater
management systems.
This project aims to address the critical need for a thorough understanding of the impact of
climate change on urban stormwater management and the development of adaptive strategies
to enhance resilience.

Asphalt concrete stands as the predominant construction material used throughout Kenya for
pavement surfacing. However, conventional asphalt concrete exhibits multiple constraints such
as:
1. Susceptibility to Environmental Strains: Environmental factors like UV radiation,
water penetration, and temperature variations can degrade the asphalt concrete over
time. This leads to a loss of binding agents, increased brittleness, and ultimately,
structural failure.
2. Rutting and Deformation: Heavy traffic loads can cause rutting, deformation, and
