Gelatinizer mother liquor for porous water-permeable concrete and preparation method thereof

Abstract

The invention discloses a gelatinizer mother liquor for porous water-permeable concrete and a preparation method thereof. The gelatinizer mother liquor comprises, by weight, 57.0-58.0% of water, 19.0-20.0% of calcium chloride, 2.0-2.5% of ferrous chloride, 2.5-3.0% of ferrous sulfate, 3.0-3.5% of iron chloride, 1.5-2.0% of sodium chloride, 2.5-3.0% of sodium sulfate, 2.0-2.5% of magnesium sulfate, 1.5-2.5% of potassium sulfate, 2.4-3.0% of ammonia chloride, 0.1% of a stabilizing agent and 0.1% of a dispersant. The preparation method comprises respectively mixing the above materials and water to obtain a calcium chloride solution, an iron chloride solution, a magnesium sulfate solution, a potassium sulfate solution, a ferrous chloride solution, a ferrous sulfate solution, a sodium sulfate solution, a sodium chloride solution and an ammonia chloride solution and mixing all the solutions. The gelatinizer mother liquor improves concrete aggregate bonding performances, water permeability after construction and anti-compression and anti-bending strength, is convenient for maintenance, has a long novel road maintenance period, has mixing uniformity and improves production efficiency.

Description

technical field [0001] The invention relates to a gelling agent for porous and permeable concrete, in particular to a gelling agent mother liquor for porous and permeable concrete and a preparation method thereof Background technique [0002] In recent years, with the acceleration of urbanization and industrialization, there are many high-rise buildings, the population is highly concentrated, the ecological damage is serious, and the living environment is in urgent need of improvement. At present, cities are mostly covered by reinforced concrete, and the road surface has poor water permeability and air permeability. Rainwater cannot penetrate in time, resulting in serious urban water accumulation and insufficient groundwater supply. In addition, ordinary road concrete has a strong heat absorption capacity under the condition of sunlight, which makes the temperature of the road rise, which brings great inconvenience to people's life. Permeable concrete is an eco-friendly con...

Problems solved by technology

[0003] At present, there are many types of gelling agents developed and sold on the existing market, most of which are powders, and powder gelling agents need to add other admixtures or stone powder admixtures when mixing porous and permeable concrete. Other admixtures or stone powder admixtures are not stirred uniformly, resulting in low aggregate bond strength, water permeability and compressive strength; due to the above defects, liquid gelling agents developed in recent years, such as China The publication number disclosed in the patent is CN104496393A, a multi-purpose concrete gelling agent and its preparation method. After the formulation of the gelling agent is prepared, it is mixed with concrete to form a permeable concrete, but the permeable concrete cannot achieve the desired result after the construction is completed. performance and practical requirements, and its solidification speed is slow, and the gelling agent has a low dissolution rate and uniformity with the concrete when preparing permeable concrete, which leads to a reduction in production efficiency and cannot meet engineering requirements; furthermore, The above method is used to prepare the gelling agent, so that ice water or cold water needs to be frequently added to cool down during the preparation process, which affects the production efficiency when producing the gelling agent, and reduces the use effect and practical performance.
