Both OPC and PPC cements are good for concrete slab construction - just ask PC Concreting Canberra. OPC is the cement most commonly used in industrial and large constructions, PPC is most commonly used for small residential constructions. PPC is used when the chances of sulfate attack are greater, since it has good sulfate resistance compared to OPC. Ordinary Portland cement is the most commonly used type of cement, which is suitable for all general concrete constructions.
It is the most commonly produced and used type of cement worldwide, with an annual global production of around 3.8 million cubic meters per year. This cement is suitable for all types of concrete constructions. Type 1 is common Portland cement (OPC), which is a general purpose material. Type 4 is a low-temperature cement that radiates less heat as it sets and dries.
Used for applications where too much heat is not desired. Type 5 cement is highly resistant to sulfates and is used for contact with highly alkaline soil and water. White cement is prepared from iron oxide-free raw materials and is similar to Portland cement except for its white color. It is more expensive and used for architectural purposes, such as prefabricated curtain walls and interior and exterior decorative work, such as cladding slabs, floors, ornamental concrete products, and garden paths.
Hydraulic cements, such as the types IL, IS, IP and IT mentioned above, are archetypes of hydrophobic cement. They are impervious to water and set quickly, leading to their use in underwater structural and waterproofing applications. It is also quite strong and resistant to corrosion and rust. However, hydraulic cement doesn't work well at colder temperatures.
Soil material in soil-cement can be almost any combination of sand, silt, clay, gravel, or crushed stone. Local granular materials, such as slag, caliche, limestone rock and slag, as well as a wide variety of waste materials including ash, fly ash, foundry sands, and quarry and gravel screens, can be used as soil material. Old roads with a granular base, with or without bituminous surfaces, can also be recovered to obtain an excellent concrete floor. The construction of the interstate highway system, during the 1960s and 1970s, was considered by many to be a heyday for concrete paving and road construction in general.
Road Designers Stopped Requiring Contractors to Build Thicker Roads at Edges. Concrete roads were generally six inches thick in the middle and eight or nine inches thick at the edges and allowed construction with a uniform concrete depth, saving time and money. The invention of the slipform paver in 1949 was another milestone in the development of concrete paving technology, as it allowed road crews to place large sections of concrete continuously and therefore much more efficiently than before. Therefore, the advantage of this cement is that the formwork can be removed earlier, which increases the speed of construction and lowers the construction cost by saving formwork costs.
Sulfate-resistant cement is used to reduce the risk of sulfate attack on concrete and is therefore used in foundation construction where the soil has a high sulfate content. The Pennsylvania Turnpike, built on a railroad right of way during the 1930s, was the first major intercity toll highway or toll road in the United States and was built with concrete. With cement carrying air, air gaps in the concrete provide space for water to expand without cracking the concrete. .
