EFFECT OF STYRENE-ACRYLIC EMULSION ON MECHANICAL PROPERTIES OF CEMENT-BASED COMPOSITES

Desheng Xiong, Fuqin Han, Mo Chen Mo Chen

چکیده


Cement-based composites were prepared from rice husk and styrene-acrylic emulsion (SAE) with a semi-dry production process. The dosage of SAE, the rice husk content, and alkali treatment on the mechanical properties of the composites were studied. The mechanical test of the rice-husk cement composites proved that SAE is an effective additive for reinforcing the composites, and the mechanical properties improved significantly by alkali treatment and adding SAE. The composites were characterized by FT-IR, SEM, and XRD. The results indicated that SAE can be beneficial for the hydration of the composites.
