聚丙烯酸酯乳液改性粉煤灰/水泥砂浆的制备与性能研究(英文)

Preparation and Mechanical Properties of Polyacrylate Latex Modified Fly-Ash/Cement Mortar

以纯丙乳液为有机添加剂,制备了粉煤灰/水泥砂浆,研究了不同粉煤灰和纯丙乳液用量对砂浆抗压、抗折及粘结强度的影响。砂浆的抗折及粘结强度得以改善,但抗压强度有所降低。

In this communication, pure polyacrylates latex （PL） as organic additive, fly ash （ FA ）, Portland cement as inorganic binders （IB） , and river sand as fine aggregate were studied. Compressive strength, adhesion strength, and flexural strength were investigated with dosage of FA and PL. The flexural strength and adhesion strength of the mortars are improved. However, the compressive strength decreases with increase of FA and PL.
