Masonry is a major structural material for low rise buildings, however the design of masonry buildings is rarely taught as a formal course at most universities. As part of the educational experience and to become familiar with the specifications and testing procedures for grouted masonry, a student run experiment on varying the water to cement ratio of masonry grout was conducted. The purpose is to report on the effects of changing the water-to-cement (W/C) ratios in a standard grout mix. The typical W/C ratio is approximately 0.80:1.00. In order to show the effects of increasing water in a grout mix, a second grout mix was investigated – a 1.00:1.00 W/C ratio. The two W/C ratios investigated were a 0.74:1.00 and a 1.00:1.00 W/C ratio. Students prepared and tested the 0.74:1.00 grout mix per the standard of the American Society of Testing and Materials (ASTM) Standard C476 Table 01: Conventional Grout Proportions by Volume, and the ASTM Standard C1019: Standard Test Method for Sampling and Testing Grout.
