Due to the high costs of traditional concrete materials in Nigeria, such as river sand, there is an increasing demand to explore alternative materials like laterite for fine aggregates. Although laterite is abundant in Nigeria, its full potential in the construction industry remains untapped. Previous studies have shown that partially replacing river sand with laterite produces concrete with competitive strength properties. This research aims to validate and extend these findings, evaluating the impact of different aggregate sizes (12 mm, 20 mm, and 40 mm) on the strength of concrete with 10% and 25% laterite replacements for fine aggregate. Results revealed that as the laterite percentage increased, compressive, flexural, and split tensile strengths decreased. While 0% and 10% laterite replacements met the required strength, the mix with 25% laterite fell short. Increasing maximum coarse aggregate size led to higher strengths, with 40 mm sizes exhibiting the highest, and 12 mm the lowest. Compressive strengths ranged from 22.1 to 37.6 N/mm2, flexural strengths from 4.07 to 5.99 N/mm2 and split-tensile strengths from 2.93 to 4.30 N/mm2. This research highlights the need for meticulous mix design adjustments when using laterite, balancing workability with strength objectives. The developed regression models offer a valuable tool for predicting concrete properties based on mix parameters, providing insights for optimizing laterized concrete designs across diverse construction applications and supporting sustainable building practices.

Sugarcane bagasse ash is an offshoot of sugar factories found after burning of sugarcane bagasse which itself is found after the extraction of sugar from sugarcane. The disposal of this material causes environmental problems surrounding sugar factories. Sugarcane bagasse ash is rich in silica that can play the role of an effective pozzolana which leads to improve pozzolanic reactions resulting in better performing building materials. Light weight concrete can be prepared from low density bagasse ash. Surface reactions are improved due to its high specific surface area. Some percentage of cement is replaced with bagasse ash to determine the fresh and hardened properties of the concrete mix. Compressive strength of the concrete can be improved tremendously on later stages of addition of bagasse ash. Incorporating sugarcane bagasse ash in concrete can further alter the other various performance of concrete. Keywords—sugarcane bagasse ash, pozzolana, fresh and hardened properties.

Concrete is second most used material after water. It has found major application in the construction of buildings, roads, bridges and drainage systems, among others. It is however very expensive due to the cost of its constituent materials. These are cement, sand (fine aggregate) and gravel (coarse aggregate). In addition to financial cost, the production of cement involves emission of a lot of carbon dioxide (about 2.8 tonnes annually world wide), contributing to about 8% of the world's CO2 emissions. There are alternative concretes being developed through research that are attracting attention especially those of them with cheaper and waste components. These include Laterite concrete, Concretes from Geopolymers. Concretes from pozollanas and Fibre concretes and mortars. These along with others will be presented in this chapter.
