Assessment of standardization of sandcrete blocks production in lagos: case study of alimosho local government area, Lagos Nigeria

The paper assesses the quality of sandcrete blocks in some selected areas of Alimosho Local Government Area (LGA), the north eastern part of Lagos state, Nigeria. With the view of enhancing the quality of the production of sancrete blocks in the state. The study is hybrid in its methodological approach. Combining, the quasi experimental research method with the survey and desk top method.  A total of 24 manufacturers were randomly taken and all of whom had questionnaires administered on them, samples of their product- sandcrete blocks were taken and subjected to laboratory tests on, sieve analysis, water absorption capacity and compressive strength analysis.
