Highlights

  • The wall is a main component of any building and carries out important functions such as bearing loads, provide fire protection, heat and sound insulation, and provide protection against environmental and weather conditions

  • Different kinds of masonry materials have been used for the construction of building walls in Sri Lanka

  • Rate of slipping of formwork depends on the feeding speed of cement quarry dust mixer, moisture content and rate of compaction

Summary

Introduction

The wall is a main component of any building and carries out important functions such as bearing loads, provide fire protection, heat and sound insulation, and provide protection against environmental and weather conditions. The main drawbacks of using conventional clay bricks are lack of clay, low strength, and high production cost and time. In early 80’s, Kulasinghe [2] first introduced slip form technology as an alternative wall construction method to burnt clay brick walls or cement sand block walls. The conventional slip form wall construction method is fully manually operated, and system has identified several drawbacks while constructing a wall, such as uneven compaction due to manual compaction, high compaction and shutter lifting time etc. The first true slip form system was developed in 1903, when contractors began supplying lifting power to the forms by screw jacks positioned outside the form through the use of wooden jacking legs
