Optimizing strength low cement pumpable

项目摘要

Newcrete Investments Limited Partnership is in the process of producing pumpable concrete with low-cementcontent for various applications to provide their customers top quality concrete products at competitive prices.However, their attempts failed to produce pumpable concrete with sufficient workability and/or strength. Themain purpose of this project is to develop novel low-cement concrete mixtures with relatively highcompressive strength, slump, and sufficient pumpability. The project will examine the feasibility of usingviscosity modifying admixtures (VMAs) and supplementary cementing materials (SCMs) to improve thecompressive strength, slump, and pumpability of low-cement content concrete. The research program willconsist of a series of laboratory tests on the slump and compressive strength to determine the optimum dosageand type of both VMAs and SCMs. Some selected successful mixtures will then be tested under full-scalepumping tests at the company's facilities to assess the pumpability followed by a statistical analysis of theresults. The findings of this research will contribute to the company's future applications of low-cement contentpumpable concrete by allowing them to offer high quality products at relatively low cost. This collaborationwill result in a potential growth of the company (additional employees and expanding their product line) and toeventually benefit the Canadian economy.

Newcrete Investments有限的合作伙伴关系正在生产可泵式混凝土，并以低凝位的方式生产各种应用程序，以便以有竞争力的价格为客户提供顶级优质混凝土产品。该项目的目的是开发新型的低水泥混凝土混合物，具有相对较高的强度，低迷和足够的泵送性。该项目将检查使用粘度修改混合物（VMA）和补充胶结材料（SCM）的可行性，以提高低污物含量混凝土的压缩强度，亏损和泵性。研究计划将对有关底板和抗压强度进行一系列实验室测试的研究，以确定VMA和SCM的最佳Dosageand类型。然后，一些成功的混合物将在公司的设施进行全范围内测试中进行测试，以评估泵送性，然后对其中的统计分析进行测试。这项研究的发现将通过允许以相对较低的成本提供高质量的产品，从而为公司的低水位含量混凝土的未来应用做出贡献。这种合作将导致公司的潜在增长（额外的员工并扩大其产品线），并为加拿大经济带来益处。
