SHOTCRETE Shotcrete, or sprayed concrete are all terms used to describe concrete or mortar that is delivered via a hose and pneumatically projected at a high velocity onto the surface. Shotcrete is a cement-aggregate-water combination that is often reinforced with traditional steel rods, steel mesh, or fiber. Shotcreting is carried out with the assistance of …
How Shotcrete and Concrete Differ from Each Other? How Shotcrete and Concrete Differ from Each Other? When beginning a building job, you must decide on the materials to utilize. Whatever you’re constructing, you want it to be safe and durable for decades, and concrete is a popular method to do this. A kind of concrete …

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 …
Slump Cone Test for Concrete Workability In this article “Slump Cone Test for Concrete Workability”, the workability of concrete is defined and slump test is described. What is Concrete Workability? The quantity of beneficial internal labor required to achieve complete compaction without encountering the aforementioned concrete difficulties. Internal useful work is the effort or energy …
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, …
How High-Strength Concrete differ from Normal Concrete? How High-Strength Concrete differ from Normal Concrete? According to the compressive strength value, concrete may be classified as either normal-strength concrete or high-strength concrete (HSC). Normal-strength concrete usually obtains a compressive strength that ranges between 20 and 40 MPa. On the other side, HSC will possess a compressive …

Segregation of Concrete Segregation of concrete is defined as the process of separating the ingredients of a heterogeneous mixture so that their distribution becomes irregular. Additionally, segregation refers to the separation of new concrete components, resulting in a non-uniform mix. This is a separation of coarse aggregate from the mortar that occurs as a result …
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% …

Test to Calculate the Consistency of Cement Test to Calculate the Consistency of Cement: The Cement Consistency Test is used to determine the normal consistency of every cement paste. Additionally, the consistency value is used to determine the initial setting time, final setting time, and soundness of cement, as well as the strength parameter of …
