彩色透水混凝土的改性及其施工工艺

本文采用聚羧酸粉剂减水剂对萘系粉剂减水剂生产的透水混凝土胶结剂进行改性。实验表明,在每吨胶结剂中减水组分用量采用聚羧酸粉剂减水剂只需要萘系粉剂减水剂的五分之一,有效降低成本500元/t左右,使用聚羧酸粉剂减水剂制备的胶结料透水率、凝结时间、抗压强度、粘结力度等方面都优于萘系粉剂减水剂制备的胶结料,且易于施工;本文采用科之杰自制的封闭剂对透水混凝土进行着色及保护,与聚氨酯树脂封闭剂、脂肪族二元酸脂封闭剂相比,120天后依然不褪色、不起皮,使透水混凝土抗酸碱,耐候性强,美观大方;文中并对透水混凝土的施工工艺进行了阐述,以供混凝土行业探讨。

Modification and construction process of colorful permeable concrete

In this paper, polycarboxylic acid reducer powder was used to modify the cementing agent of permeable concrete produced by naphthalene series powder. The study showed that the dosage of poly carboxylic acid water-reducing agent used in cementing agent per ton was only one fifth of naphthalene water-reducing agent. Eventually, effectively, the cost of about 500 yuan/t was reduced, in addition, permeable rate, setting time, compressive strength and bonding strength were superior to the cementing agent of naphthalene series, and easy to construction. The colouring and protection of permeable concrete were made by using the sealant made by KZJ. Compared with polyurethane resin sealant and fatty acid ester, it is still not faded and unfurled after 120 days, so that permeable concrete is resistant to acid and alkali, and has strong weatherability and beautiful appearance. In the end, the construction technology of permeable concrete is expounded, so that it can be discussed and refered by the concrete line.
