SLURRY INFILTRATED FIBER CONCRETE



1. INTRODUCTION
1.1 General

Slurry infiltrated fiber concrete (SIFCON) is a relatively new special type of high performance steel fiber-reinforced concrete (HPFRC). SIFCON is made by preplacing short discrete fibers in the moulds to its full capacity or to the desired volume fraction, thus forming a network. The fiber network is then infiltrated by a fine liquid cement-based slurry or mortar. The fibers can be sprinkled by hand or by u ....etc

The Application of Back Propagation Neural Network of Multi-channel Piezoelectric Quartz Crystal Sensor for Mixed Organic Vapours

Abstract
A multi-channel piezoelectric quartz crystal sensor with a
homemade computer interface was prepared and employed in the
present study to detect mixture of organic molecules. Back
propagation neural network (BPN) was used to distinguish the
species in the mixture organic molecules and multivariate linear
regression analysis (MLR) was used to compute the concentration
of ....etc

Fiber Reinforced Concrete
What is a Fiber ?
Small piece of reinforcing material possessing certain characteristic properties.
Can be circular or flat.
Parameter used to describe fiber Aspect ratio .
Aspect ratio is ratio of its length to its diameter.
Typical aspect ratio for fibers ranges from 30 to 150.
What is Fiber Reinforced Concrete (FRC)?
Fiber reinforced concrete (FRC) is concrete containing fibrous material which increases its structural integrity.
It contains short discrete fibers that ....etc

The challenges posed by the modern structural requirements demand materials with increasingly improved properties such as strength, stiffness, impact and abrasion resistance. The focus of research shifted to developing high performance materials in this decade. Fibre reinforced concretes prepared with different types of fibres have found many structural applications. However, the ductility of fibre reinforced concrete basically depends on the volume fraction of fibres used in the production though various other factors such as type of fibre, it ....etc

New materials and construction techniques are required to provide Civil Engineering alternatives to traditional road construction practices. Traditional techniques have not been able to withstand the burden of mixed traffic for a long time. Therefore, the pavement requires overlap. To overcome this problem the inclusion of fibre in pavements is adopted today. This paper highlights the use of discrete fibre in road construction. Recently, geosynthetics have been used to reinforce and separate the base course material for aggregate surface roads ....etc
