彩色砌筑(或勾缝)砂浆是装饰混凝土砌块砌体的主要配套材料,其力学性能和收缩性能对砌体相当重要。本文就三种颜料在不同掺量情况下对砌筑砂浆的用水量、强度和收缩性能影响,进行试验研究,结果表明:①掺加颜料有助于降低砂浆的用水量。②当氧化铁红和氧化铁黄两种颜料掺量为3%时,砂浆强度有所提高;掺量超过3%时砂浆强度呈现不同程度的降低;相反,绿色颜料在掺量为12%以内时,砂浆强度均高于不掺者。③颜料掺量较低时,砂浆收缩率低于不掺者,但当继续增加颜料掺量,则砂浆收缩率将有所增大。
Color masonry (or pointing seam) Mortar is the main supporting material for masonry concrete masonry. The mechanical properties and shrinkage properties of masonry are very important. In this paper, the effects of three pigments on the water consumption, strength and shrinkage of masonry mortar under different dosage were studied. The results showed that: (1) Adding pigment can reduce the water consumption of mortar. ② When the content of red iron oxide and yellow iron oxide is 3%, the mortar strength is increased. When the content of the iron oxide red and iron oxide yellow is 3%, the mortar strength is reduced to some extent. On the contrary, when the content of green pigment is within 12% Mortar strength are higher than those not doped. ③ pigment content is lower, the mortar shrinkage rate is lower than those who do not, but as you continue to increase the amount of pigment, the mortar shrinkage rate will increase.
