An Analysis of the Influence of Some Structural Properties on the Production and Sales of 225mm Hollow Sandcrete Block in Minna

Abstract

This is a research work on the influences of structural properties on the sales and production of 225mm hollow Sandcrete block in Minna metropolis. A test was conducted to examine whether or not there are statistical relationships between some structural properties such as bearing load, crushing load, strength and marketing efficiency of the block. Employing both simple and multiple regression analysis and testing at 95% confidence level it was discovered that structural properties have no significant relationship with marketing efficiency (that is, sales and production). The research showed R-Square of 1.87, 0.67 and 0.90% respectively for strength versus marketing efficiency; strength versus bearing load; and crushing load versus marketing efficiency respectively. However, there is a statically relationship between sales and production. In addition, the result showed R-square of 63.50% with probability value less than 0.05% confidence limit. It was concluded that sales of 225mm hollow Sandcrete block is largely influenced by rate of production and that marketing efficiency has no relationship with the compressive strength, crushing and bearing loads of the hollow blocks studied.
