Reasons Why Concrete Needs Waterproofing Reasons Why Concrete Needs Waterproofing:Â Concrete waterproofing is critical in below-grade locations to avoid water infiltration and structural damage. We have depleted the supply of construction sites with the desirable drainage pattern inherent in formerly plentiful high-ground terrain in many parts of the globe. As a result of this attrition, we’ve …
High Strength Concrete: Coarse Aggregates High Strength Concrete: Coarse Aggregates: The characteristics of coarse aggregates hold more effect in case of high strength concrete (HSC) compared to normal strength concrete, since HSC is significantly influenced by the interfacial transition zone. Some basic properties of the aggregates are shape, maximum particle size, maximum nominal particle size, …
Concrete with Glass as an Aggregate Concrete with Glass as an Aggregate: Typically, concrete is composed of sand (which is the fine aggregates) plus various sizes of crushed rocks and gravel. However, how about using glass as concrete aggregates? There is growing direction towards using alternative materials into concrete, with the glass being one of …
Waste Glass in Concrete Waste Glass in Concrete: As per a report by the United States Environmental Protection Agency, total waste material production raised from 89 to 260 million tons from 1961 to 2015. In 2015, 27% of waste materials were recycled and 10% were composted. Furthermore, 13% was combustible with energy recovery and 53% …

Generic Types of Cement Generic Types of Cement: Cements have a variety of properties and features that vary according to their chemical composition. Cement may be made to possess a variety of properties by altering the fineness of the grinding or the oxide composition. Historically, continuous attempts have been made to develop various types of …
Chemical Composition of Portland Cement Chemical Composition of Portland Cement: Cement is mostly composed of lime, silica, alumina, and iron oxide as raw materials. At high temperatures, these oxides react with one another to form more complex compounds. Along with the rate of cooling and fineness of grinding, the relative proportions of these oxide compounds …
Use of M Sand for Concrete Use of M Sand for Concrete: Manufactured sand (or referred to as M-Sand) is a concrete building material that can be used in place of conventional (river) sand. By crushing tough granite rocks, manufactured sand is made. The crushed sand is cubical in form with grounded edges that has …
Water Required for Hydration of Cement Water Required for Hydration of Cement: C3S needs 24% water by weight of cement, while C2S requires 21%. Additionally, it has been estimated that approximately 23% of the water in cement by weight is needed for chemical reaction with Portland cement compounds. Since this 23% of water chemically reacts …
