Application Of Ferro-cement In Contruction

INTRODUCTION
Ferro-cemnt is a relatively new material consist of wire meshes and cement mortar.
Developed by P.L.Nervi,an Italian architect in 1940.
Widely used due to the low self weight,lack of skilled workers,no need of framework etc¦.
Quality of ferrocement works are assured because the components are manufactured on machinery set up and execution time at work site is less.
Maintenance cost is low.
Ferro-cement construction has come into widespread use only ....etc

Concept of Cement

The word ËœCEMENTâ„¢ may be defined as a substance, which can join two or more pieces of same other substance together to form a unit mass. Cement is a fine powder which when mixed with water and allow to set and harder can join different components together to give a strong structure mechanically. Thus cement can be used as founding material for bricks or for founding solid particles of different sizes (rubble masonry ) to form a monolish.
It was about 150 years ago or so that ËœCem ....etc

Abstract
The germicidal effectiveness of various additives when blended within a microstructure of a cement based system was studied. The relationship between the chemical and physical characteristics of concrete surfaces and their ability to have an enhanced resistance to algal growth was documented through a novel set of laboratory and field testing. The main potential areas of application for these new cement composite systems involve the lining of canal surfaces where fixed-surface biocides are desirable to control biofouling. Different b ....etc

 SPECIFIC GRAVITY:
WEIGHT OF EMPTY PYCNOMETER (M1) : 324.5g
WEIGHT OF PYCNOMETER + RICE HUSK ASH (M2) : 355.9g
WEIGHT OF PYCNOMETER + RHA + WATER (M3) : 856.3g
WEIGHT OF PYCNOMETER +WATER (M4) : 871.7g
SPECIFIC GRAVITY OF RHA : M2-M1 / (M2-M1)-(M4-M3)
= 1.96

PRODUCTION DEPARTMENT
I was in production department, I Shaw and understood various processes to make clinker and cement. Main reaction process occurs in kiln at 1400C to make clinker. To make cement grinding and rubbing processes take in cement mill. Main process is as below:
 MINING:
They have two types of mining process: Conventional mining (Blast mining) and Eco-friendly surface mining. In blast mining, Drill a hole with the help of drilling machine and fill the explosive material into that hole, ....etc

ABSTRACT

This test method covers determination of the compressive strength of hydraulic cement mortars, using 2-in. or cube specimens.Test Method C 349 provides an alternative procedure for this determination (not to be used for acceptance tests). This test method covers the application of the test using either inch-pound or SI units. The values stated in either system shall be regarded separately as standard. Within the text, the SI units are shown in brackets. ....etc

Introduction
Cement-treated or cement-stabilized soils have been used in pavement
base, subbase, and subgrade construction since 1915 because
cement has been effective in improving the engineering
properties of a wide variety of soils, including granular materials,
silts, and clays
PCA 1992. Usually, cement-treated soils are
mixed with low cement dosages with or without a targeted
strength, depending on their functions, whereas the cementstabilized
soils are mixed with high cement dosages with a targeted
st ....etc
