Cement pavement repair material is a multi-component polymer material composed of composite special cement clinker, polymer resin, ultra wear-resistant aggregate, etc. This product has simple construction, high strength, and good toughness, and is an ideal material for modern concrete cement pavement repair.

Quality assurance of non shrink cement grouting material for Yantai Longkou structural reinforcement grouting material

Application scope:
Mainly used for repairing concrete roads and factory cement floors, treating cement pavement peeling, sanding, freeze-thaw, salt erosion, exposed stones, honeycombs, and rough surfaces. This product is widely used for rapid repair of concrete in bridges, docks, water conservancy, high-speed rail, nuclear power, large-scale municipal engineering, and other fields.

Product Features:
1. High intensity.
2. Rapid strength growth: Standard maintenance state: The strength of the repair material can reach over 20Mpa after one day, and it can be opened to traffic in 2-4 hours under normal weather conditions.
3. Waterproof and anti-seepage performance superior to concrete: After pouring cracks with early strength repair materials, the micro expansion function of this product can fill and expand the slurry inside the cracks, providing sufficient waterproof and anti-seepage effects.

Using spray coating method to achieve continuous and seamless waterproof insulation layer, forming seamless roof and overall external wall insulation shell, with excellent waterproof and anti-seepage performance; The self-adhesive performance (without the need for any intermediate bonding materials) is strong in bonding with the roof and exterior walls, and has good wind resistance and resistance to negative wind pressure; Whole spray coating construction, completely eliminating hot spots and cold bridges; Flexible gradient technology can effectively prevent cracking of the waterproof layer; Mechanized operations, automatic batching, and quality are all fast and have a short construction cycle; Stable chemical properties, long service life, and no pollution to the surrounding environment; It extinguishes itself from an open flame and only carbonizes without dripping during combustion. The size and shape of the carbonization layer remain basically unchanged, effectively blocking the entry of air and preventing the spread of fire, with good fire safety performance.
4. The amount of water added is 16% to 18% of the weight of the repair material, which is 8-9 kilograms of water per bag of material
Construction method:
1. Before use, it is necessary to clean the loose materials and dust on the surface of the repaired concrete, and only when there is no visible water can construction be carried out.
2. When mixing, the repair material should be mixed evenly according to the water consumption provided in the instructions (i.e. 8-9 kilograms of water per bag) before pouring for construction. If the pouring area and volume are too large, a small amount of fine stones or large sand can be added to reduce concentrated exothermic reactions. Pour the mixed slurry into the area that needs to be repaired, compact and smooth it, and cover it with plastic film and water it for curing in a timely manner after the repair slurry has finally set. In winter, it is necessary to cover it with cotton felt for insulation protection.

In modern housing construction, bay windows are commonly designed in residential buildings, which is loved by the public. With the popularity of the public, this area has also become a key focus of decoration. When decorating bay windows, everyone likes to choose high-end stone paving, among which bay window marble is a commonly used type. The advantage of bay window marble is that it can provide a good brightness for one's home. This way, the emission of marble can make the room bright, and the bay window made of marble stone is not easy to fade and can maintain its original brightness continuously. What should we pay attention to when laying marble on bay windows in order to make the entire decoration flawless? There are four main points to note: unevenness and straightness of multiple spliced bay window panels; excessive deviation in length and width of processed bay window panels, and inconsistent thickness.
3. Road opening hours: Depending on the customer's design intensity and construction season, the fast opening hours are 2-8 hours.
Attention: This product is packaged in 50kg/bag (kraft paper composite bag)
Storage conditions: Dry environment for 12 months without affecting use

Whether it is reinforcing or repairing stone, the temperature of the working environment must be considered when implementing the operation. Whether it is the resin used for reinforcement, the adhesive used for repair, or the filling solution used for filling, the reference time for solidification is measured at an ambient temperature of 25 ℃. In general, their solidification time decreases with increasing ambient temperature and extends with decreasing ambient temperature. If the ambient temperature is too high and the solidification time is too short, it will increase the working speed of the operators and affect the quality of the operation; Low ambient temperature will result in excessively long solidification time, affecting the entire production process, affecting yield, and reducing reinforcement strength and adhesion.
