Concrete consists of a mix of ingredients including portland cement pozzolans water coarse aggregates fine aggregates and additives. concrete may also contain mineral colors granulated blast-furnace slag and blended cements. when fresh cement can be molded hours after it is produced.
Concrete intended for railway structures tra c structures. the work describes a speciﬁc inﬂuence of aggregate and mineral additives on abrasive resistance of concrete 7. some studies show that good concrete resistance is ensured by using a higher strength class.
Concrete is a porous material having high gas vapour and liquid permeability leading to deterioration of reinforced concrete structures. one of the ways to protect rc structures from corrosion is to use protective coatings. frequently the coating is the main option to protect the concrete structures .
Concrete is a stone like substance obtained by permitting a carefully proportioned mixture of cement sand and gravel or other aggregate and water to harden in forms of the shape and of dimensions of the desired structure. long horizontal or inclined members with limited width and height are called beams. their main function is to transfer loads from the slab to the columns.
Concrete is one of the oldest and most common construction materials in the world mainly due to its low cost availability its long durability and ability to sustain extreme weather environments.
Concrete placement should be followed by proper finishing compaction and curing practices to get the best benefits. modern plaster additives. modern plaster additives are available in both powder or liquid form and can be used for site production or for large scale industrial production of dry-mix plaster.
