Properties of Mortar from Portland Cement when Adding Concentrated Latex Modified with Nonylphenol Ethoxylate Surfactant

Abstract

In this study, the compressive strength, flexural strength, tensile strength, and abrasion resistance of mortar containing latex treated with nonionic surfactants were evaluated. Nonyl Phenol Ethoxylate (NPE) by utilizing the ratio of latex to cement that has been fortified with NPE. by weight, they were 0.0, 2.0, 4.0, 6.0, 8.0, and 10.0. The samples were evaluated at ages 7 and 28 days. The results showed that the compressive strength of the mortar tended to decrease with the increasing percentage of NPE and the flexural strength of the cement mortar when added with concentrated latex modified with NPE from the % 0 to 2 percent at 28 days of curing, causing the flexural strength of cement mortar to increase from 85.76 kg/cm2 to 88.01 kg/cm2 and tensile strength of cement mortar Tar was higher when added with 2% NPE modified concentrated latex at 28 days of incubation, increasing from 60.86 kg/cm2 to 72.87 kg/cm2 and abrasion resistance. It was found that the abrasion resistance of the cement mortar increased with the addition of concentrated latex modified with NPE at all ratios. The conclusion is that the NPE mixed with the concentrated latex has high dispersion and prevents the rubber from clumping before it is combined with the cement. The rubber will then contribute to the formation of a film and mortar-incorporated rubber fibers. Consequently, both bending and tensile strength are enhanced.
