Masonry’s Resistance to Driving Rain: Mortar Water Content and Impregnation

Effect of mortar water content in the properties of masonry

Water content affects mortar and masonry properties however, it is often determined by the mason assessing mortar workability. This can lead to lack of consistency and variable masonry performance. This paper investigates the compressive, flexural and bond strength and stiffness of brick masonry bound with natural hydraulic limes (NHL2, 3.5 and 5), hydrated lime (calcium limeCL90s) and cement-l...

Influence of Mortar Water Content on the Strength of Lime Mortar Masonry

Water content affects mortar properties and the quality of the resultant masonry, however, it is often subjectively determined by the mason by assessing workability. This lack of explicit methodology and data, can lead to lack of mortar consistency and field performance, adversely affecting full uptake of lime mortars into mainstream technology. The aim of this research is to assist develop con...

Resin impregnation of cellulose nanofibril films facilitated by water swelling

Flexible composite films were produced by impregnating aqueous phenol formaldehyde (PF) resin into water-swollen cellulose nanofibril (CNF) films. CNF films were prepared using a pressurized filtration method in combination with freeze drying. The freeze-dried films were swollen with water then impregnated with PF resin by soaking in aqueous resin solutions of varying concentrations. Small amou...

Determination of the Water Content in the Porous Structure of Mortar By Means Of Micromechanical Models and Ultrasonic Velocity

The application of cementicios materials is widely extended fundamentally for its use as structural elements. In this sense, it presents some advantages respect to other materials, in spite of the different physical and chemical attacks that limit its durability. This durability is a function of its porous structure, because the existence of pores facilitates the destructive agents which attack...
