为了解决有关白水泥混凝土的行为和性能的问题，设计了一项研究计划，对I型灰色和白色硅酸盐水泥进行比较研究。对用两种不同的水泥制成的水泥浆和水泥砂浆的性能进行了测试和比较。试验结果表明，白水泥浆体凝结时间短，砂浆抗拉、抗压极限强度高于灰水泥；对新拌混凝土样品的试验结果表明，用白水泥配制的初拌和终拌的坍落度较大，时间较短。对硬化混凝土样品进行的试验表明，白色水泥柱具有更高的极限抗压强度。最后，全尺寸的钢筋混凝土梁，除了水泥类型不同之外，都被设计成在剪切或弯曲中失效。测试结果表明，没有差异可以归因于所使用的水泥类型。
To address questions concerning the behavior and performance of white cement concrete, a research program was designed to conduct comparative studies of type I gray and white portland cements. Different properties of cement paste and cement mortar, made with the two different cements, were measured and compared. Test results indicated shorter setting time of white cement paste and greater ultimate tensile and compressive strength for its mortars than the corresponding values for the gray cement.Results of tests on samples of fresh concrete indicated greater slump and shorter rimes of initial and final set of mixes prepared with the white cement. Tests conducted on samples of hardened concrete indicated greater ultimate compressive strength of the white cement cylinders. Finally, full-scale companion reinforced concrete beams, identical except for the type of cement, were designed to fail in shear or in flexure. Test results indicated no difference that could be attributed to the type of cement used.
