This study developed hydrophobic mica powder (HMP) using and stearic acid through high-temperature stirring to enhance cement mortar's resistance freeze–thaw (F–T) cycles in sulfate environment. Initially, the impact of HMP content on water absorption compressive strength was assessed. Further tests mortar with varying dosages evaluated under F–T cycles, including mass loss rate, relative dynamic modulus elasticity (RDME), strength. Results indicated that modified reduced by 62.75% 5.43% compared unmodified mortar. After 125 showed minimal damage, a 7.33% RDME reduction 9.12% decline. Detailed stress–strain curve analysis led an axial compression constitutive model incorporating effects contents. paper elucidates mechanism HMP, demonstrating its potential improve experimental microscopic analysis.

Mica is a harmful substance in sand and occurs frequently. The application of super standard mica difficult problem large-scale engineering. In this work, the effects an interface modifier, mineral admixture, curing system on properties cement-based materials with were studied. strength linearly decreases content sand. When exceeds 6%, compressive mortar concrete at 28 d by more than 22.3% 33.5%, respectively. By adding silane coupling agent (SCA) 50% mass natural conditions, increases 10.9%. SCA are suitable for performance will not be affected appropriate amounts admixture. drying shrinkage strain concrete, containing high modified SCA, reduced 10.5%, diffusion chloride ions reduced. XRD results show that addition interfacial does change hydration products. MIP SEM can form bridge structure between products mica, improve bonding zone, reduce number pores.

Abstract This study enhances the water resistance of mica paper/organic silicone resin composites through surface modification with 3-aminopropyltriethoxysilane (APTES). The Fourier-transform infrared spectroscopy and X-ray photoelectron confirmed formation chemical bonds between APTES mica. results showed that at an optimal concentration 0.6%, diffusion coefficient decreased from 5.0 × 10 −3 mm²/min to 2.7 mm²/min, permeability 5.71 −4 1.94 a significant reduction in equilibrium uptake. Additionally, modified exhibited minimal mechanical strength loss after moisture aging, demonstrating excellent resistance. interface shear tests revealed 28.6% increase interfacial bonding modification. demonstrates potential silane coupling agents enhance performance inorganic polymer composites, providing theoretical support for their industrial application.
