This project aims to investigate why geopolymer concretes crack less than the Portland cement concretes. Carbon emissions from Portland cement is second only to fossil fuels. Geopolymer may emit less carbon dioxide than Portland cement concrete because it bleeds less and has higher creep. The project will test this hypothesis on geopolymer and Portland cement concretes, and emulate its findings in all types of concretes. The project intends to create a specific market for geopolymer by developing a crack-free pavement and floors technology, while understanding cracking in concrete will reduce cracking issues.

本项目旨在研究为什么地聚合物混凝土比波特兰水泥混凝土裂缝少。波特兰水泥的碳排放量仅次于化石燃料。地聚合物可能比波特兰水泥混凝土排放更少的二氧化碳，因为它的渗水更少，蠕变更高。该项目将在地聚合物和波特兰水泥混凝土上测试这一假设，并在所有类型的混凝土中模拟其发现。该项目旨在通过开发无裂缝路面和地面技术为地聚合物创造一个特定的市场，同时了解混凝土的裂缝将减少裂缝问题。
