Many buildings in Canada are built using concrete beams and columns as primary load-bearing members. These beams and columns are built using cement concrete and steel reinforcement bars known as steel rebars. Steel rebars are susceptible to corrosion and thus, many reinforced concrete buildings develop cracks leading to safety concerns. This NSERC research project will develop a narrow concrete beam that fits well with prefabricated insulated light-gauge steel wall panels and supports the load safely. These prefabricated wall panels are only 6 in. (150 mm) wide which are required to be used to move towards the implementation of modular construction method which is a fast, economical, and green approach for constructing buildings. Steel rebars cannot be used for making such narrow beams since about 50% of the beam's width or 3 in. (75 mm) will have to be spared as the protecting corrosion cover for the steel rebars. A possible solution to this problem is to use non-corrosive rebars. Hence, this research will develop a new technology for designing and constructing narrow concrete beams using basalt fiber made rebars called BFRP rebars which are corrosion resistant and hence, do not need any protecting concrete cover. BFRP rebars are also stronger, lighter, and are green materials. These rebars are made from a volcanic rock called Basalt. Development of this new concrete beam design and construction technology will allow the industry partner, Bear Construction and Engineering Inc. to adopt the modular construction method and BFRP rebars in future building projects. The other industry partner, MEDA Engineering & Technical Services will also be able to use the new technology in future buildings and other infrastructure project designs. MEDA is also the sole distributor of BFRP rebars and hence, this partner is expected to see a growth in the sale of BFRP rebars. Thus, with the completion of this research project, both partner organizations will gain a competitive edge allowing them to grow their businesses faster and creating new jobs in Canada. The implementation of the modular construction method will also help the environment by reducing waste.

加拿大的许多建筑物都是使用混凝土梁和柱作为主要负载成员建造的。这些横梁和柱是使用水泥混凝土和钢筋钢筋制造的，称为钢钢筋。钢制钢筋容易受到腐蚀的影响，因此，许多钢筋混凝土建筑会产生裂缝，从而引起安全问题。该NSERC研究项目将开发一个狭窄的混凝土梁，非常适合预制的绝缘轻型钢制墙板，并安全地支撑负载。这些预制的墙板只有6英寸（150毫米）宽，需要用于实施模块化施工方法，这是一种快速，经济和绿色的建筑方法。钢钢筋不能用于制造如此狭窄的光束，因为大约50％的梁宽度或3英寸。（75毫米）必须保留作为钢钢筋的保护腐蚀盖。解决此问题的一种可能解决方案是使用非腐蚀性钢筋。因此，这项研究将开发一种新技术，用于使用玄武岩纤维制成的钢筋设计和构建狭窄的混凝土梁，称为BFRP钢筋，它具有耐腐蚀性，因此不需要任何保护混凝土盖。 BFRP钢筋也更强，更轻，是绿色材料。这些钢筋由称为玄武岩的火山岩制成。这种新的混凝土梁设计和建筑技术的开发将使行业合作伙伴，Bear Construction and Engineering Inc.能够在未来的建筑项目中采用模块化构造方法和BFRP钢筋。 MEDA工程和技术服务的另一个行业合作伙伴还将能够在未来的建筑物和其他基础设施项目设计中使用新技术。 MEDA还是BFRP Rebars的唯一分销商，因此预计该合作伙伴将看到BFRP Rebars的销售增长。因此，随着该研究项目的完成，两个合作伙伴组织都将获得竞争优势，使他们能够更快地发展业务并在加拿大创造新的就业机会。模块化施工方法的实施也将通过减少废物来帮助环境。
