Strength and Water-Repelling Properties of Cement Mortar Mixed with Water Repellents [PDF]

open access: yesMaterials, 2021
In this study, the compressive strength and water contact angle of mortar specimens prepared by mixing two types of water repellent with ordinary Portland cement (OPC) and rapid-hardening cement mortar were measured before and after surface abrasion.

Hydrologic behavior of model slopes with synthetic water repellent soils [PDF]

open access: yes, 2017
In the natural environment, soil water repellency decreases infiltration, increases runoff, and increases erosion in slopes. In the built environment, soil water repellency offers the opportunity to develop granular materials with controllable ...

Interactions with water of mixed acetic-fatty cellulose esters [PDF]

open access: yes, 2011
Cellulose powder was acylated with mixtures containing acetic, fatty and acetic-fatty anhydrides to form acetic-fatty cellulose esters. The total degree of substitution (DS) of the mixed cellulose esters (MCE) ranged from 2x10-2 to 2.92.

How roughness controls the water repellency of woven fabrics

open access: yesMaterials & Design, 2020
The coming ban on substances of high environmental concern used to provide water repellency to fabrics creates new challenges for the textile industry. Here we show that the design of the texture of woven fabrics is an important parameter to play with in

Effect of Biomass-Burning Emissions on Soil Water Repellency: A Pilot Laboratory Study

open access: yesFire, 2021
While western U.S. wildfires have increased in intensity and scale, their impacts on soil chemical composition and hydraulic processes have received little attention, despite increasing erosion, surface runoff and flooding.

Intensity and Persistence of Soil Water Repellency in Pine Forest Soil in a Temperate Continental Climate under Drought Conditions

open access: yesWater, 2018
Although soil water repellency (SWR) has been reported under different soils, climates, and vegetation types of the world, especially in forest land and following wildfires, the understanding of this variable continues to be rather limited.

Use of Clay Dispersed in Water for Decreasing Soil Water Repellency [PDF]

open access: yes, 2017
In this study, we examined the efficiency of a kaolinite clayey soil to mitigate water repellency of a sandy soil with olive trees. The treatment was applied to the soil zone below the tree canopy, which displayed the highest degree of water repellency ...

Synthesis and Performance Analysis of Green Water and Oil-Repellent Finishing Agent with Di-Short Fluorocarbon Chain

open access: yesMolecules, 2023
A novel fluorine-containing water-repellent agent (OFAE-SA-BA) was designed and synthesized by emulsion copolymerization, which was used to replace the commercial long fluorocarbon chain water-repellent agent.

Selection of the Optimum Carrier for Manufacturing Water-Repellent Concrete and Durability Evaluation of Cement Mortar Using It

open access: yesApplied Sciences, 2020
The purpose of this experiment was to complement the shortcomings of existing surface treatment methods and to implement water repellency inside concrete to prevent water penetration and improve the durability of concrete.

Effects of household water-repellent agents and number of coating layers on the physical properties of cotton woven fabrics.

open access: yesPLoS ONE, 2023
The increased interest in outdoor activities has prompted the demand for water-repellent fabrics that can withstand various environmental factors. In this study, the water repellency and physical properties, namely thickness, weight, tensile strength ...
