Cement: What are Reactive Powder Mortars with Calcium Aluminate Cement?
Mortars composed of fiber and silica fume reinforced Calcium Aluminate Cement (CAC) perform better at low water/cement ratios. These mortars contain metal fiber reinforced CAC and silica fume under constant workability. Moreover, the admixture also consists of fine aggregate (0.1-1 mm) and copolymer acrylic polyester-based plasticizer. Thanks to using very fine aggregate in the mixture, […]
Calcium Sulphate Effect: What are Self-Leveling Screeds?
Leveling screed is a leveling material which is known as self-leveling screed as a cement-based polymer modified self-leveling material. Self-Leveling Screeds are used to correct deformities and level the floors. These are easily applied of floors. They create a substrate after they harden which is ideal for ceramic coating or using other coating options. We […]
What is White Concrete? Where to Use?
The key property of white concrete that differentiates it from gray concrete is its white color. The whiteness of concrete comes from the color and purity of raw materials it contains. Therefore, the source, shape, purity, and color of raw materials used in white concrete affect its whiteness degree. In addition to providing aesthetic and […]
White Cement and Pumice Manufacture
White cement has high strength characteristics with its high bond strength and adhesion strength in addition to being aesthetic. High early strength property of white cement helps to increase the manufacturing speed as well. This also reduces formwork removal time. It also provides quite high levels of dosage advantage thanks to its final strength higher […]
Glass Fiber Concrete Additive: Alkali-Resistant Glass Fiber-Reinforced Concrete
By nature, concrete exhibits low tensile strength, brittleness, unstable crack propagation, low breaking strength, and inadequate ductility. These shortcomings are generally eliminated through conventional reinforcement or pre-strain applications in reinforced concrete structures without having improvement in the properties specific to concrete. Alternatively, it was found that strength and ductility of concrete are increased by including […]
How Does Calcium Aluminate Cement Age?
Calcium aluminate cements differ from Portland cements (OPC) in terms of both mineralogical and physical characteristics. The raw materials for Portland cement are primarily sourced from clay and limestone, so the primary oxides are CaO and SiO2. Calcium aluminate cement, on the other hand, is rich in alumina because the source of the raw material […]
Portland Cement and the Mechanism in Acceleration of Hardening: Adding Calcium Aluminate Cement
When calcium aluminate cement is added to Portland Cement the hardening acceleration mechanism changes. Mixtures made only with Portland cement may be inadequate in terms of offering solutions to various problems such as high temperatures, early strength, rapid setting and preventing cracks. This is why binding systems referred to as ternary binding systems are created […]
