Generally, glass fibre reinforced concrete (GFRC) had intermediate characteristics between rigidity and compressive strength of cement and high tensile strength of glass fibre. Besides that, GFRC shown 20 times of its impact of asbestos cement. This fibre gave two to three times of flexural strength of normal reinforced concrete (Neal et al, 1978). Based on theoretical mechanics of cement and concrete stated that tensile failure began with micro crack and microcrospic separation. As a result, cohesive crack existed where it will produce break on concrete.

Light-weight, versatility, and tight sealing are the benefits of using plastic valves for domestic plumbing applications. Anyway, you can't use plastic valves for applications where high temperatures are involved, so a valve made of a metal is the best choice for such applications. Ball Valve applications: Ships, oil rigs, gas plants, bioprocessing, water treatment, chlorine manufacturing, pharmaceutical, fire protection, and beverage are the common applications of this versatile valve type. So, you can understand its special capabilities here. High-pressure, high-temperature, safety, quick shut-off, and reliability are the factors that make this valve type the best type available on the market today.
Both reinforced thermosetting resin pipe (RTRP) and Reinforced polymer mortar pipe (RPMP) are fiber glass pipe. Fiber glass pipe grades are mainly classified according to the type of resin employed such as epoxy, polyester and vinyl ester pipes. The manufacturing process for fiberglass pipe include filament winding and centrifugal casting.
Rip raps are generally used in conjunction with other structures to fortify and further protect coastlands and is used mainly in this regard for extra fortification purposes or when finances are low and a quick and efficient structure is required for coastland protection. (FSC, 2015) Pros 1. They do not suffer from wave scour like seawalls 2. They are cheap and efficient
Some of these structures need to be upgraded or replaced, because they are in poor condition, not only due to deterioration processes, but also due to errors made during design and execution. Strengthening on reinforced concrete (RC) structure with Near-surface mounted (NSM) fiber-reinforced polymer (FRP) reinforcement has been done in recent years. Strengthening and corrosion issue solved by use of this NSM FRP reinforcement include the optimization of construction details, models for the bond behaviour between NSM FRP and
Methods such as Cured-in-place (CIPP) refer to a method of lining in which a flexible tube filled with a thermosetting resin produces a pipe after resin cure whereas Sliplining (SL) is a general term used to describe methods of lining with continuous pipes and lining with discrete pipes (“United Kingdom Society of Trenchless Technology,” n.d.). Some benefits to be gained from the use of trenchless renewal methods in the improvement of existing infrastructure include avoiding possible damage to adjacent structures, homes, and businesses caused by dewatering operations; avoiding public inconvenience, installations in tight spaces and minimizing disturbances in environmentally sensitive areas. Unfortunately these have a higher dollar cost than that of their open cut
Research Statements My research interest span the 3D simulation and experimental approach to the use of High Performance Fiber Reinforced Autoclaved Aerated Concrete (HPFR/AAC) with a focus on architectural application. I am particularly interested in fiber reinforced concrete technology used to optimize some mechanical properties of final products. During my master’s degree, I applied this principle in my thesis research titled, “Behavior of Steel-Polypropylene Hybrid Fiber Reinforced Concrete”, which is focused on mechanical behavior of concrete elements based upon fiber types and volume percentage. As a civil engineer, I am interest in investigating an alternative material with excellent properties as a substitute for ordinary concrete which is one of the key challenges that building engineers and architects tackle every day. Literature In Recent years, concrete as one of the oldest construction material, has been widely used in construction
Non-metals cannot conduct electricity or heat very well. As opposed to metals, non-metal elements are very brittle, and cannot be rolled into wires. The non-metals exist in two of the three states of matter at room temperature gases and solids. Alkali Metals are made up of six different elements and are found in group one on the periodic table. These metals have only one electron in their outer shell.
