ABC STUDIES AND ANALYSIS OF CONCRETE UNIT PRICES

Génie Civil

This article is the continuation of our articles, published on the same site IJARIIE which have a reference ISSN (O): 2395-4396, Paper id: 11241, whose title is the contribution to the study of high-compact fluid concretes: formulations and characterizations; and a Paper id 11270, a title of Modelling of fluid concretes by experimental designs. After the formulation and modeling of the three ordinary concretes and twenty-one high-compact fluid concretes, the study and the price analysis of these concretes were carried out. These concretes are formulated from the same materials, but the quantity and dosage that make them different. We referred to the quantities of gravel, sand, cement, water and admixture, to be able to evaluate the unit prices of concretes. The unit prices of concretes generally depend on the price of materials, on the wages needed to pay for labour and on the amount of money that must be set aside to provide for the depreciation of materials and tools. Various overheads are also included in the unit prices. In order to make a decision on the use of concrete types on the construction site, the ABC analysis allows evaluating concretes that have the lowest prices but good qualities.
