PPC Cement Good for Waterproofing is a common choice in the construction sector because of its strength and toughness. The cement consists of gypsum, OPC clinkers, and pozzolanic materials, such as calcined clay, volcanic ash, and silica fumes. These constituents are added in specific quantities (15% to 35% by weight).
With regards to waterproofing, PPC cement good for waterproofing is considered as a debatable choice. Let’s explore the characteristics and examine its viability.
PPC Waterproofing or Water-Resistant?
Waterproofing is a process in which a flat or corrugated surface is coated with a thin or thick layer of chemical-based liquid or membrane. On the other hand, a water-resistant material resists the permeability of water (to a certain extent).
PPC cement is a water-resistant material; it is not effective in sealing a surface completely. To attain complete waterproofing, additional measures are required, such as waterproofing membranes, admixtures, or coatings.
PPC cement is a versatile product; it is used in construction of hydraulic structures, mass concreting, and marine works. Some of its properties are as under:
More durability: PPC cement offers higher resistance against chemical attacks because of the reaction between pozzolanic materials and cement, which produces Calcium Silicate Hydrate Gel.
Low hydration heat: This cement releases less heat during the hydration process, which helps to prevent cracks and ensure more strength to the concrete.
Good workability: PPC cement is easier to handle and maintain, ensuring better workability of the concrete mix. It is optimal for complex shapes and intricate designs.
Environmentally friendly: The use of pozzolanic materials reduces the amount of clinker required, resulting in lower carbon emissions and smaller carbon footprint.
Improved cohesion: PPC cement produces a more cohesive concrete mix, which improves strength and durability.
Lower water demand: The use of pozzolanic materials in PPC cement reduces the water demand for the concrete mix, which reduces the overall cost.
What is the difference between PPC Cement and Ordinary Cement?
PPC and Ordinary cement are used in construction. The main differences are:
Composition
PPC cement contains pozzolanic materials like volcanic ash, calcined clay, gypsum and clinker whereas OPC is composed of clinker and gypsum.
