By adopting VSKB, the huge manpower engaged in this industry will not only safeguard their livelihood but can also live in better workplaces with limited pollution.īrick kilns first started in pits and walls were added later. This article presents a review of the various kiln technologies and suggests that the vertical shaft brick kiln (VSBK) should be used as an alternative to the polluting traditional kilns. In October 2018, the Supreme Court empowered Environment Pollution (Prevention and Control) Authority (EPCA) to ensure that all brick-kilns implement the “zig-zag” technology, as specified by the Ministry of Environment and Forests, which can reduce emissions by 80 percent. These moves are because traditional brick-kilns cause air pollution as they use coal in the brick-making process. The National Green Tribunal (NGT) too had ordered that digging of earth for making bricks without prior environment clearance (EC), be banned.

If the Government bans burnt clay bricks, it would be a big blow to the brick-kiln industry. The Ministry of Housing and Urban Affairs (HUA) is examining whether it can ban use of burnt-clay bricks in its construction projects, a move aimed to boost environment-friendly products. For India’s brick industry to survive, it should modernize its kilns. In developed countries, the simple kilns have been replaced by continuous tunnel kilns that produce millions of high-quality bricks in less time. After China, India is the second largest manufacturer of bricks, producing over 10 percent of the global production, and has about 140,000 brick-making enterprises, which accounts for 250 billion brick masonry units (The industry employs about 15 million workers and consumes over 35 million tons of coal annually. Brick manufacture in India and also in some parts of the world still use the traditional firing technique.

The second objective is to compare the Young's Modulus for the masonry prisms to the mean peak stress for the prisms. The first objective is a determination and comparison of the quasi-statically measured Young's Modulus and the dynamically measured Modulus of Elasticity for masonry prisms. There are three objectives to measure the material properties for this paper. Material properties are required for these methods of analysis, irrespec-tive of the numerical method. The design of build-ings within Australian now must consider the minimum loading from the AS 1170.4 SAA Earthquake Loads using either an equivalent static loading, frequency domain or time domain analysis. 2 INTRODUCTION A reasonable proportion of the larger masonry buildings and dwellings built within in Australia and elsewhere in intraplate regions would have been designed on the basis of static loading design rules and assuming zero or low seismic loads. A single type of mortar was used for all experimental work. The dynamic and quasi-static samples were tested from the same population of masonry prism samples. A test rig has been developed for measuring the elastic properties of masonry prisms under uniaxial static loading.

The third aim is to compare the masonry prism results to masonry unit results for the Young's Modulus, to determine the ratio of Young's Modulus to the peak stress for the prisms and to cal-culate the Young's Modulus for the mortar. The second aim is to compare the dynamic Modulus of Elastic-ity results to the Young's Modulus obtained using quasi-static methods. The first aim of this paper is to experimentally investigate the use of high frequency sinusoidal dynamic loading to determine the dynamic Modulus of Elasticity of masonry.

These two dynamic procedures are to be tested on masonry prisms to provide a verification of the methods. The Longitudinal Vibration Test Method and the Ultrasonic Pulse Methods were developed for the dynamic testing of concrete speci-mens. One of the parameters identified as influencing the structural response of buildings is the dynamic Modulus of Elasticity of masonry.
