Summary of Research

The topic of research is ‘Performance of Laterized Concrete.’

The use of laterite as a substitute for sand in concreting works is inevitable especially in the developing nations of Africa like Nigeria, where the material is cheap and readily available in large deposits while the cost of procuring sands (fine aggregates) like other conventional construction materials has been on increase on daily basis. However, most of the previous studies only investigated laterised concrete as compressive members, and just a little has been done on investigating the performance of reinforced laterized concrete units subjected to tensile loads.

The project will involve experimental work to investigate properties of fresh and hardened laterized concrete, both short and long term. A number of material mechanical properties such as compressive   strength, bond strength and stiffness characteristics under various environmental and service conditions from both macro and micro structure level will be exposed. Specialised technologies and expertise, such as the use of scanning electron microscopy and the other tools used for petrographic analysis, will be used to investigate the micro-structure of this material. The stiffness damage test together with the more traditional test methods such as ultrasonic pulse velocity will be explored to assess and qualify the integrity of samples made from such materials  under various environmental conditions simulated in the laboratory.

The progress made to date includes investigation of samples of laterite found in Northern Island, U.K. and another one from Ghana, Africa where X-Ray Fluorescence and X-Ray Diffraction test are being carried out for chemical analysis and mineralogy contents respectively. A sample of laterite from Nigeria is being expected for the same investigation for comparison.

The outcome of the research will clear all doubts on possibilities of using laterised concrete as a construction material most especially as a structure member in tension and fully integrate  laterite into concreting works thereby making it possible for Nigeria to meet its target of providing shelter for all citizens at affordable prices by the year 2020.
