THE COMPRESSIVE STRENGTH OF CONCRETE MADE USING CEMENT PRODUCED IN TANZANIA

This paper presents the compressive strength of concrete made using cement produced in Tanzania. The data presented in this paper is based on extensive laboratory testing of the concrete cube compressive strength made at different water-cement ratio using cement from four factories manufacturing cement in Tanzania. The relationship between the water-cement ratio and cube compressive strength are presented. The developed tables can serve as a starting point for carrying out concrete mix design using cement produced in Tanzania and can be used by prospective bidders to estimate the amount of cement required to produce a certain grade of concrete during bidding.本文报告了采用坦桑尼亚本土生产的水泥制备的混凝土的抗压强度数据。本文所用数据源自对坦桑尼亚四家水泥厂生产的水泥、按不同水灰比（water-cement ratio）制备的混凝土立方体试块抗压强度开展的大量室内试验。文中同时给出了水灰比与混凝土立方体试块抗压强度之间的相关关系。本文编制的相关表格，既可作为采用坦桑尼亚产水泥开展混凝土配合比设计的参考基础，也可供潜在投标人在投标阶段估算制备某强度等级混凝土所需的水泥用量。
