We are importers and suppliers of an excellent quality range of APP Waterproofing Membrane from Egypt. This waterproofing membrane is one of the largest selling membrane used in waterproofing solutions. Manufactured using 160 gsm polyester core coated by Atactic Polypropylene bitumen and Polyethylene film on both sides, this waterproofing membrane is acknowledged widely for its durability, chemical stability and strength. The offered APP Waterproofing Membrane is available in different specifications to meet the varied needs of our esteemed clients.
Super Mat plain membranes are ideal for a wide range of waterproofing applications such as:
Super Mat Membranes With Mineral Top Finish
Super Mat also comes with Mineral Top finish. The upper surface is coated with minerals. The bottom surface, like Super Mat, has Polyethylene. The rest of the construction is similar to Super Mat.
Size And Thickness:
Both Super Mat and Super Mat MT come in thickness of 3 mm and 4 mm and in rolls of 1m x 10m.
Chemical admixtures are the ingredients in concrete other than cement, water, and aggregate that are added to the mix immediately before or during mixing. Contractors use admixtures primarily to reduce the cost of concrete construction; to modify the properties of hardened concrete; to ensure the quality of concrete during mixing, transporting, placing, and curing; and to overcome certain emergencies during concrete operations.
Successful use of admixtures depends on the use of appropriate methods of batching and concreting. Most admixtures are supplied in ready-to-use liquid form and are added to the concrete at the plant or at the jobsite. Certain admixtures, such as pigments, expansive agents, and pumping aids are used only in extremely small amounts and are usually batched by hand from premeasured containers.
The effectiveness of an admixture depends on several factors including: type and amount of cement, water content, mixing time, slump, and temperatures of the concrete and air. Sometimes, effects similar to those achieved through the addition of admixtures can be achieved by altering the concrete mixture-reducing the water-cement ratio, adding additional cement, using a different type of cement, or changing the aggregate and aggregate gradation.
Water-reducing admixtures usually reduce the required water content for a concrete mixture by about 5 to 10 percent. Consequently, concrete containing a water-reducing admixture needs less water to reach a required slump than untreated concrete. The treated concrete can have a lower water-cement ratio. This usually indicates that a higher strength concrete can be produced without increasing the amount of cement. Recent advancements in admixture technology have led to the development of mid-range water reducers. These admixtures reduce water content by at least 8 percent and tend to be more stable over a wider range of temperatures. Mid-range water reducers provide more consistent setting times than standard water reducers.
