- Fibre-reinforced concrete
HEADNOTE Past, present and future Although considerable development work on fibre-reinforced concrete is currently in progress, little information is available regarding the history of this construction material. The purpose of this paper is to discuss the development of this material from antiquity until the present day. The paper will also ......
- Comparing fiber performance: ASTM C 1399 gives
producers an easy way to measure the toughness of fiber reinforcement in
concrete.
Producers have long been touting the benefits of fiber-reinforced concrete, helping concrete contractors understand how fibers improve the quality and durability of flatwork. Now, recent research and marketing initiatives are enabling producers to communicate to design engineers and code enforcement officials the benefits of fibers in load-bearing concrete applications such ......
- Fibre-reinforced polymers in construction - Strengthening concrete structures
HEADNOTE The need to structurally upgrade deteriorated, damaged and substandard infrastructure has become one of the most important challenges facing asset owners across the world. The construction materials used include concrete, masonry, wrought iron, cast iron and steel, and most structures are now over 50 years old. The infrastructure sector ......
- Effects of recycled materials on the properties ofwood fiber-polyethylene composites--Part 2: effect of a compatibilizeron the wettability of birch plywood and polyolefins.
Abstract This study examined the effects of a compatibilizer on the wettability of birch plywood and polyolefins. The compatabilizer was a low molecular weight emulsion type maleated polypropylene (MAPP), Epolene E-43. The polyolefins investigated included low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), and polypropylene (PP). For E-43 treated wood surfaces, ......
- Characterizing the failure of composite
structures.
When two or more materials combine to create a better material system, they form a composite. In a broad sense, metal alloys and plastics are composites, but their constituent materials are combined at the microscale. In a narrower sense, a composite material is one in which the constituent materials are ......
- Lenton form saver eliminates protruding dowel bars in segmental pours
IMAGE PHOTOGRAPH 1 Dowel bars, the reinforcing steel that protrudes through formwork, have long been the traditional method for joining bars in segmental pours. In recent years, many contractors and construction product suppliers have discovered that dowel bar substitutes can improve their schedules and the bottom line by eliminating costly ......
- Thin concrete overlayment - without cracks
IMAGE PHOTOGRAPH 1 The new Marks & Spencer 'Lifestore' at the Metro Centre, Gateshead, included a 225mm-thick traditional reinforced concrete slab. In order to achieve a high-quality finish to the wearing surface of the retail units, the slabs were overlaid with a low shrinkage, fibre reinforced concrete screed, or overlayment, ......
