Abstract

This article provides an estimation of the future demand of construction materials in Colombia and necessary minerals to produce them by using systems dynamic and analysis of materials flows. Through the analysis of materials flows the amount of minerals required for the production of cement and concrete are determined. Required production of cement and concrete is estimated through a model of systems dynamic, which is adjusted with data from DANE construction census. Results indicate that, disregarding the secondary offer of materials, 176.9 million tons of ground aggregates, river sand, gray cement, dead rock, and cooked ceramic would be required. Manufacture of cement and concrete would require 15.4 million tons of lime, 14.9 million tons of gravel, 14.1 million tons of gypsum, and 13.3, 9.7, and 9.3 million tons of clay, iron minerals, and sand, respectively.

通过物流分析和系统动力学预测哥伦比亚的建筑材料需求
本文通过系统动态和材料流动分析,对哥伦比亚未来建筑材料的需求以及生产这些材料所需的矿产进行了估计。通过对物料流的分析,确定了生产水泥和混凝土所需的矿物质量。水泥和混凝土的所需产量是通过系统动态模型估计的,该模型根据DANE建筑普查的数据进行了调整。结果表明,不考虑材料的二次报价,将需要1.769亿吨地面骨料、河砂、灰色水泥、废石和熟陶瓷。水泥和混凝土的生产将分别需要1540万吨石灰、1490万吨砾石、1410万吨石膏以及1330万吨、970万吨和930万吨粘土、铁矿物和沙子。
