NEW TECHNIQUES OF EROSION CONTROLS ON HILL ROADS

INTRODUCTION
Transportation contributes all round development of a country and hence plays a vital rate towards its progress. If the highways are not properly located and may contribute sediments to streams. The control of soil and water is basic to the protection of the road structure and therefore highway design, construction and maintenance must be continually evaluated to minimize erosion and sedimentation problems

Polymers in concrete have received considerable attention over the past 25 years. Polymer-impregnated concrete (PIC) was the first concrete polymer composite to receive widespread publicity. PIC has excellent strength and durability properties, but it has few
commercial applications. Polymer concrete (PC) became well known in the 1970s and is used for repair, thin overlays for floors and bridges, and for precast components. Polymer-modified concrete (PMC) has been used primarily for repair and overlays. Several limitations have slowed the use ....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
SPECIFIC GRAVITY OF RHA = 1.96
BULK DENSITY :
EMPTY WEIGHT OF CALIBRATED CONTAINER : 47g
WEIGHT OF CONTAINER + RHA : 96.6g
VOLUME OF CONTAINER :100 cm3

BULK DENSITY OF RHA = (96.6-47) / 100
= .496 g/cm3
= 496 kg/m3 ....etc

Cement and Concrete Terminology


FOREWORD
This report is the authoritative glossary for cement and concrete technology. It is to be used generally and specifically in ACI technical
communications, correspondence, and publications. One mission of Committee 116 is to produce and maintain a list of terms
with their meaning in the field of cement and concrete technology.
Committee 116 has tried to produce a glossary that will be useful, comprehensive, and up-to-date. It recognizes, however, that the
listing ....etc

INTRODUCTION

Light emitting polymers or polymer based light emitting diodes discovered by Friend et al in 1990 has been found superior than other displays like, liquid crystal displays (LCDs) vacuum fluorescence displays and electro luminescence displays. Though not commercialised yet, these have proved to be a mile stone in the filed of flat panel displays. Research in LEP is underway in Cambridge Display Technology Ltd (CDT), the UK.

In the last decade, several other display contenders such as plasma and field emission displays wer ....etc

ELECTROACTIVE POLYMERS(EAP)
ABSTRACT
Electro active polymers are soft actuation materials that are fastly replacing the conventional actuating materials such as piezo electric crystals, motors, screws etc:- As the name suggests, they essentially consists of a ionic polymer back bone metallic composite having positive counter ions. On the application of an electric field or small voltage, these EAP s will bend towards the anode.
They have properties resembling human muscles and ar ....etc
