Abstract

The invention belongs to the field of construction, and specifically discloses an ECP wallboard supporting grouting material and a preparation method thereof. The ECP wallboard supporting grouting material comprises the following components in percent by weight: 10-40% of cement, 10-30% of early-strength cement, 30-75% of medium and fine sand, 0.001-1% of a high-molecular cellulose ether polymer,0.01-2% of engineering fiber, 0.1-10% of an expansion agent, 0-5% of an early strength agent and 0.1-5% of a water reducing agent. The wallboard supporting grouting material provided by the inventioncan effectively solve the problem of drying shrinkage of the existing grouting material and is convenient and fast to construct and rapid to form; generally, the curing cycle of the cement grouting material can be completed within 2-3 days after grouting, and the grouting material can be permanently formed, so that tight connection of the grouting material and a concrete component is guaranteed, the water-proof and impermeable performance of the grouting material are improved, the durability of the grouting material is improved, the curing cycle is shortened, the construction efficiency is improved, and the construction cost is reduced. The preparation method of the grouting material is simple, the cost is low and the construction is convenient and fast.

Description

technical field [0001] The invention belongs to the technical field of construction preparation, and in particular relates to a matching grouting material for ECP wall panels and a preparation method thereof. Background technique [0002] Grouting material refers to various grouting material mixtures or cement polymer mixtures produced by specialized manufacturers and used in construction projects. It is a new type of building material developed in my country in recent years. It can be divided into ordinary Ready-mix grouts and specialty grouts. Ordinary grouting materials mainly include ground self-leveling grouting materials and grouting materials for component bonding. Special grouting materials include epoxy resin grouting materials and early-strength emergency repair grouting materials. [0003] With the technological progress of the construction industry and the improvement of civilized construction requirements, on-site ready-mixed grouting materials are increasingly...
