2.1.8.4. Tensile strength: Lightweight and normal weight concretes have similar tensile strengths, though lightweight exhibits greater variability. The tensile strength of normal weight concrete of equal compressive strength may vary within a wide range depending, among other parameters, on the shape and surface texture of the aggregate. Experimental tests indicate that the tensile strength of concrete is highly variable and ranges from a bout 8-12% of its compressive strength. The actual value depends

been used in many sectors for over 20 years as it has excellent properties in terms of high tensile strength-to-weight ratio, corrosion resistance, durability, mouldable and good thermo mechanical properties. These excellent properties lead to the low maintenance cost for alternative construction, automotive, marine to the aerospace industries. This paper will provide the improvement in strength of FRP in which will give a significant change in engineering field and perform better materials to

compressive strength, diametral tensile strength and flexural strength levels. The results showed no statistically significant difference between the four material in terms of compressive strength(1). The main trait that is necessary for resisting intraoral forces. It was shown that Diametral tensile strength was the significantly higher for paracore than the other materials(1). The results showed a very interesting result

compulsory component in all the electronic devices. And it gives desire to its inert nature, it can not participate in any further reaction with the concrete matrix and it results in less deviation of strength parameters (Shini Shanmughan et al.). It has been done the work to describes Flexural strength and flexural modulus of the composites can be successfully improved by filling nonmetals recycled from waste

LITERATURE REVIEW 2.1General Various researches have been done to explore the benefits of using crusher stone dust in concrete unit to enhancing the properties of concrete like compressive strength, flexural strength, etc replacing cement / fine aggregate by weight or by volume. In the previous investigation, researchers used fiber like polypropylene, nylon polyester, coconut coir, glass fiber, steel fiber etc. for the enhancement of mechanical properties and partial or full replacement of ingredient

reinforced Polyester Composite has been developed to find out an alternative structural material. The physical and mechanical characteristics that are Tensile strength, Flexural strength, Water absorption, Hardness etc. illustrate the competency of the developed composite. It is found that Water Absorbency, Tensile strength, Flexural strength, hardness & stiffness increase with increasing of Metal Mat layer in the composite which is estimated maximum for the three Metal Mat layered composite and minimum

CHAPTER 6 DESIGN OF PRECAST STRUCTURAL ELEMENTS 6.1 Preamble The precast structural components are manufactured off or on the sites, transported to the site and with suitable handling and erection procedures, they are assembled so as to form a structural system. The design should cater to the conditions encountered during the various stages of construction. The Different types of precast elements manufactured are listed below. Floor and Roof units: Hollow core slabs, Double T, Single T, and Precast

One cigarette butt soaked in a litre of water for 96 hours leaches out enough toxins to kill half of the fresh or saltwater fish exposed to them. Children and animals consume these pieces of toxic trash. There are costs to the communities dealing with them and there is a biological plausibility to the idea that so many cigarette butts tossed into the environment each year may leach out chemicals that could impact human health. Furthermore, the tobacco industry has distances itself from any sense

Conventionally, in aerospace, automotive and packaging industries synthetic fiber reinforced composites are widely used because of their greater strength and stiffness. But synthetic fibers are expensive and not ecofriendly. So, of late biofibers are replacing synthetic fibers which are extensively used as reinforcements in composites and these materials are gaining popularity as potential structural materials because they are abundantly available renewable, sustainable, light weight, non abrasive
