Fire resistance is one of the key factor which aids toward durability a structure. Concrete most widely used construction material and also an effective for structural fire protection. Physical thermal properties are to measure concrete. Three main reasons concrete are: non-combustible, non-toxic, low conductivity (concrete retain slow rate heat transfer). The lower value behaves like perfect s...

As the number of discarded tyres continues to increase, causing serious environmental problems, need recycling waste tyre rubber become extremely urgent in worldwide. Today, there is an increasing focus on recyclable materials. The reuse concrete contributes sustainable development. In past 10 years, numerous experiments recovery from produce products have been conducted. this review, we conclu...

The reuse of construction and demolition waste is a necessary way to achieve greater sustainability in building, introducing the criteria so-called circular economy design production process new materials. This research focuses on analyzing properties mortars made with recycled aggregates from concrete reinforced aramid fibers. For this purpose, an experimental campaign was carried out, includi...

Today concrete is most widely used construction material due to its good compressive strengt h and durability. Depending upon the nature of work the cement, fine aggregate, coarse aggregate and water are mixed in specific proportions to produce plain concrete. Plain concrete needs congenial atmosphere by providing moisture for a minimum period of 28 days for good hydration and to attain desired...

With rapid urban development, natural aggregate resources have become scarce and a large number of ageing buildings are being demolished, which has resulted in significant reduction increase construction waste. Therefore, the reuse solid waste, including waste powder recycled aggregate, attracted more attention. Additionally, as prominent way to alleviate heat island effect manage stormwater ru...

In this study, we aim to gain insight into the damage mechanisms of pervious concrete subject frost attacks in presence salt. We perform numerical simulations using a poroelastic model on system geometries representing at scale one or few aggregates: (1) aggregate coated with cement paste, (2) aggregated cracked layer and (3) two aggregates bonded paste. The indicate that is more likely occur c...

Damage to asphalt construction has made several attempts increase the strength of construction, one which is by utilizing shell waste as an mixture (filler) expected and durability pavement. The addition filler with varying levels 0%, 5%, 10%, 15%, 20%, 25% taken from percentage fine aggregate. Based on results research conducted, Marshall Test for mixtures best variations material meeting requ...

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...
