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.

We will delve into the mysteries of natural marble from four aspects: its characteristics, properties, authenticity identification, and how to maintain it. To understand natural marble, first we need to know what natural marble is? Natural marble is a metamorphic rock formed by the high temperature and high pressure within the Earth's crust from pre-existing rocks. Belonging to medium hard stone, mainly composed of calcite, limestone, serpentine, and dolomite. Its main component is carbon calcium, accounting for more than 5%. Other materials include carbon magnesium, calcium oxide, manganese oxide, and silicon oxide. The characteristics of marble are that natural marble has a dense texture but low hardness, making it easy to process, carve, grind, and polish.
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.

Previously, the scraps and sediments generated during stone processing were discarded as waste, which not only wasted resources but also polluted the environment. Yunfu City, known as the "Kingdom of Stone", once had a headache over this issue. However, since stone material companies introduced the concept of "circular economy", these wastes have transformed into treasures for making a fortune. Entering the exhibition hall of the ongoing Yunfu Stone Technology Exhibition, one can see "mosaics" and mosaics made from stone scraps everywhere. The manufacturer told reporters that these expensive collages can be sold for thousands of dollars per square meter, and the cheaper ones can be sold for only one dollar. More than 9% of them are exported to the European and American markets.
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

2、 If we want to use a specific method for external insulation facing bricks, namely the Beijing local standard "Technical Specification for External Wall External Insulation" DBJ/J1-66-22, which is an external insulation system with a steel wire mesh embedded in the cast-in-place concrete formwork, the reason why the bricks can be pasted is due to a special construction method. The principle is to set a reinforced cement mortar with good adhesion to the insulation layer, a certain thickness, and high permeability on the outer side of the insulation board. The strengthening layer is made of anti cracking mortar with a strength of M1, internally matched with 4 × 4J2 low-carbon cold drawn steel wire, and spot welded with 2.5 galvanized steel wire passing through the insulation board. This mortar strengthening layer is connected to the main structure (reinforced concrete wall) through diagonal wires and additional anchoring bars. The weight of the bricks is borne by the reinforcement layer, and the insulation layer does not participate in the stress work.
