Optimizing the strength of low-cement pumpable concrete

Newcrete Investments Limited Partnership正在生产各种应用的低水泥含量的可泵送混凝土，以提供具有竞争力的价格为客户提供高质量的混凝土产品。然而，他们的尝试未能生产出具有足够和易性和/或强度的可泵送混凝土。本项目的主要目的是开发具有较高抗压强度、坍落度和足够可泵性的新型低水泥混凝土混合料。该项目将研究使用粘度调节剂（VMA）和辅助胶凝材料（SCMs）来改善低水泥含量混凝土的抗压强度、坍落度和可泵性的可行性。研究计划将包括一系列的实验室测试的坍落度和抗压强度，以确定最佳剂量和类型的VMA和SCM。然后，一些选定的成功混合物将在该公司的设施进行全尺寸泵送测试，以评估可泵性，然后对结果进行统计分析。这项研究的结果将有助于该公司的低水泥含量泵送混凝土的未来应用，使他们能够以相对较低的成本提供高质量的产品。这种合作将导致公司的潜在增长（增加员工和扩大产品线），并最终使加拿大经济受益。

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.
