Environmental exposure to dust from quarrying activities could pose health dangers to the population living nearby. This study aimed to investigate the health effects of dust exposure on people living close to quarry sites and compared them with those who live far from the quarry sites. A crosssectional comparative study was conducted among 79 exposed participants, who lived less than 500 m ...

Abstract: This study proposes a model for optimizing the California Bearing Ratio (CBR) of loose lateritic soil mixed with quarry dust and water using Scheffe''s experimental design techniques on simplex lattice. The developed model uses a polynomial of second degree to express the behavior of the components of the mixture in a simplex lattice.
