Wet mixed mortar plasticizer (double mixed)

Product introduction

Wet mix mortar plastic retainer is a chemical additive specially used for masonry, plastering, ground, crack-resistant and waterproof mortar produced by concrete mixing stations. This product is measured and mixed according to a certain proportion of the mortar weight, and then transported to the place of use via a mortar transport mixer truck, and used within the specified time. It has the functions of reinforcing, retaining water, thickening, preventing hollow drum cracking, and improving the bonding strength of the mortar. and other characteristics, it can be widely used in various industrial and civil buildings and municipal projects.

Design Basis

《Ready-mixed mortar》( GB/T25181-2019)

《Standard for test methods for basic performance of building mortar" ( JGJ/T70-2009）

《Technical Regulations for Application of Wet Mixed Mortar" ( T/CBCA007－2021）

《Wet mix mortar plastic stabilizer》( Q/FEM001-2019）

Features

The key to the plastic retaining agent is to make the wet-mixed mortar have stable and plastic properties. This product is made up of two products, which are used together and have the advantages of easy adjustment and controllability:

A Plasticizer: Its main function is to improve the workability of mortar, has good plasticity, improves the cohesion and construction performance of mortar, and also has the functions of water retention, thickening, anti-sag, etc., and can improve various physical and mechanical properties of mortar. Chemical properties and durability.

B Regulator: The main function is to control the plastic retention time of the mortar and adjust the setting time of the mortar so that the performance of the wet mortar remains consistent during transportation, storage, and construction. The opening time can be 24 hours according to customer needs. h Internal adjustment (can also be adjusted according to construction site requirements).

Technical points

According to the customer's raw materials, the best usage ratio is made to achieve the best cost performance of the product; the dosage of this product is based on the customer's needs and is carried out under the guidance of technical personnel.

1、In principle, the fineness modulus of sand is controlled at 2.4 ~2.6mm The best, the bulk density of mortar is controlled at 1800-1900 kg/m3， Mortar with normal bulk density and viscosity can be applied smoothly and will not easily fall off when applied to the wall.

2、A Plasticizer adjusts the bulk density and viscosity of mortar.During the experimental production process, the bulk density is on the high side and can be increased appropriately. A The amount of plasticizer is used to reduce the bulk density of the mortar.

3、B The setting-regulating agent is the main admixture for adjusting the opening time of mortar. The higher the dosage, the longer the mortar will remain open. Generally, most construction sites require materials in the morning and use them up in the afternoon. The plastic retention time of the mortar is guaranteed to be able to meet the usage requirements of most construction sites within 24 hours.

4、Pay special attention to mortar in winter when the temperature is below 5 ℃No construction is allowed during this time.

5、Different varieties or brands of cement, fly ash, and sand of different materials and mud contents will also have an impact on the opening time. A mortar trial mixing experiment is required to determine the dosage.

Scope of application

This product is suitable for wet-mixed mortars of various strength levels such as artificial masonry, plastering and mechanical spraying of river sand and machine-made sand.

Packaging and storage

1、The liquid of this product is transported by tanker; the powder is sealed and packaged in composite bags, 25 kg/bag.

2、This product is valid for 3 months in liquid form and half a year in powder form.
