Book Description
This paper presents the results of a research project on the properties of masonry grout and grouted concrete masonry. Seventy-two grout specimens were tested to investigate the effect of varying the proportions of grout (cement to aggregate ratio) on the physical properties of grout and grouted concrete masonry including compressive strength and modulus of elasticity. Both fine and coarse aggregate grouts were investigated. The investigation included a comparison of the compressive strength of grout specimens saw cut from grouted hollow concrete masonry units versus the procedures of ASTM C1019 [1]. Compressive strength tests of grouted and ungrouted concrete masonry prisms were also conducted. This experimental investigation concludes that grout having leaner proportions (cement to aggregate ratio) than permitted by ASTM C476 [2] may be more compatible with typical concrete masonry units. It is recommended that the strength requirements of grout be developed as an alternate to the current proportion requirements of ASTM C476 in order to encourage designers to specify grout with properties similar to the properties of the concrete masonry units thus achieving compatibility of the components and improve the structural performance of grouted concrete masonry structures. It was also found that grout specimens molded in accordance to ASTM C1019 can be used to predict the strength of grout in grouted concrete masonry.

Effect of Mortar Properties on Strength of Masonry

Book Description
The physical properties of mortars, the bond strength of the mortars to masonry units, and the structural strength of concrete masonry and composite masonry walls containing the mortars are discussed and compared. All of the mortars were tempered to as wet a consistency as could be conveniently handled by the mason. The compressive strength of the walls increased, in general, with the compressive strength of the mortar. The racking and flexural strengths of the walls increased with the bond strength of the mortar. The strength of bond test specimens tended to increase with the compressive strength of the wet consistency mortars that were used. However, bond strength appeared to be the dominant factor affecting the racking and flexural strength of the walls. Increase in both bond strength and wall strength with compressive strength of the mortar was not proportional to the relative compressive strengths of the type N and type S mortars. The stiffness of walls subjected to compressive and flexural loads increased with the bond and compressive strength of the mortars. However, the stiffness of walls subjected to flexural loads appeared to be more dependent upon the number of bed joints in the tensile face and on their extension in bond than upon the bending strains in the masonry materials.
