Abstract Concrete is the most widely used construction material as building because it has advantages such easy workability, high compressive strength, and economical in terms of manufacturing maintenance. However, there are some disadvantages obtained from use concrete, low tensile cracking, brittleness. Therefore, necessary to add fiber concrete increase ductility SCC maintain workability aft...

A new patented lightweight aggregates is tested. This type is given the name Flashag. The only solid raw material used to manufacture these aggregates is fly ash. The aggregates are sintered but not pelletized and the process is easy and inexpensive. This paper describes these patented aggregates and compares them with other lightweight and normal-weight aggregates that are used for concrete. T...

Incorporating superabsorbent polymer (SAP), which has the abilities of absorption and desorption in concrete can achieve the effect of internal curing. The influences of the volume, particle size and ways of entrained water of SAP on the workability, compressive strength, shrinkage, carbonation resistance and chloride penetration resistance of concrete were analyzed through the macroscopic and ...

The use of supplementary cementitious materials (SCMs) in concrete manufacturing is considered as financial, technical and environmental benefit. In this regard, this paper presents the experimental and analytical study of high strength concrete (HSC) with alccofine-1203 (alccofine) and fly ash as partial replacements to cement. A total of seven mixes were prepared with different percentages of...

The Disposal of large quantity of plastic cover may cause pollution of land, water bodies and air. The proposed concrete which is made up by adding plastic in concrete may help to reuse the plastic cover as one of the constituents material of concrete, to improve the certain properties of concrete. The properties of concrete as varying percentages of plastic will test for compressive strength a...

The purpose of this study was to investigate the relationship between molarity and workability in Self-Compacting Geopolymer Concrete (SCGC), as well mechanical properties. Compressive strength split tensile tests are used characterize characteristics research. Additionally, investigates optimal for self-compacting geopolymer concrete. Fly ash lieu cement On new concrete geopolymer, is determin...

reactive powder concrete (rpc) is an ultra high performance concrete which has superior mechanical and physical properties. the rpc is composed of cement and very fine powders such as crushed quartz (100–600 μm) and silica fume with very low water/binder ratio (w/b) (less than 0.20) and super plasticizer (sp). the rpc has a very high compressive and tensile strength with better durability prope...

Many concrete structures are required to have sufficient abrasion resistance, such as dams, canals, roads and floors. The abrasion resistance of concrete may be defined as its ability to resist being worn away by rubbing. Compressive strength and aggregate type are also important factors affecting the abrasive behaviour of concrete. However, very little information on the properties of haematit...
