  • A LABORATORY STUDY INVOLVING USE OF BRICK AGGREGATE

    over burnt bricks as a source of aggregate for construction. Due to recent development in the North-Eastern region there is a huge demand of construction material especially in preparation of roads. Hence the over burnt brick aggregate can solve the problem of shortage of aggregate in this region. In bituminous concrete mix, bitumen plays the

  • Characterization of pervious concrete using over burnt

    10/05/2020· Locally available over burnt brick aggregate was used as the coarse aggregate. The microstructure of over burnt brick was observed through a scanning electron microscope (SEM) as shown in Fig. 1 and it has been observed that the surface texture of brick is very porous. It contains a large number of void spaces and micro pores with a wide dispersal of weakened crusts and grains. To

  • IS 3182 (1986): broken brick (burnt clay) fine aggregates

    0.2 Ground broken brick ( burnt clay ), commonly known as SURKHI, is also used as fine aggregate in the preparation of lime mortar where fine aggregates derived from natural sources are not available in plenty or where its cost is prohibitive. It is a good alternative to sand where

  • Use of Over-Burnt Bricks as Coarse aggregate in Concrete

    30/11/2019· The first step for preparing over burnt bricks coarse aggregate is the crushing process. After crushing of over burnt bricks the resulting material was sieved through a set of sieves. Particles whose size was less than 20mm and were retained on sieve

  • COMPARATIVE ANALYSIS OF THE COMPRESSIVE STRENGTH OF

    the brick aggregates concrete requires greater proportion of water than the normal gravel aggregate concrete. Use of broken over burnt bricks as coarse aggregate for structural concrete is recom-mended when natural aggregate is not easily available, high strength of concrete is not required and the bearing capacity of the soil is low.

  • Comparative Analysis Of The Compressive Strength Of

    coarse aggregates which are locally obtained. One such coarse aggregate is crushed burnt bricks obtained from the production of burnt bricks (Maher, 1987). 1.3 SIGNIFICANCE In many countries, the need for locally manufactured building materials can hardly be overemphasized because there is an imbalance between the demands for 3

  • A LABORATORY STUDY INVOLVING USE OF BRICK AGGREGATE

    over burnt bricks as a source of aggregate for construction. Due to recent development in the North-Eastern region there is a huge demand of construction material especially in preparation of roads. Hence the over burnt brick aggregate can solve the problem of shortage of aggregate in this region. In bituminous concrete mix, bitumen plays the

  • Study on Plastic Coated Overburnt Brick Aggregate as

    08/08/2016· Modified overburnt brick aggregate (OBBA) can solve the problem of shortage of stone aggregate to some extent. Bricks are produced from the locally available soil by burning the molded earth to desired forms. Approximately 5–10% of bricks manufactured in modern kilns are rejected because of their nonconformity with relevant specifications

  • Analysis of Overburned Brick in Concrete as a Coarse Aggregate

    such as, rice husk ash and over burnt brick aggregate as a partial or fully replacement for cement and conventional aggregates. In Nepal, bricks can be produced in the large scale and are easily available and much reliable material as crushed stone aggregate. Among the wastage or over burned bricks would help in the

  • Use of Over-Burnt Bricks as Coarse aggregate in Concrete

    30/11/2019· The first step for preparing over burnt bricks coarse aggregate is the crushing process. After crushing of over burnt bricks the resulting material was sieved through a set of sieves. Particles whose size was less than 20mm and were retained on sieve #4 (4.75mm), were used as CA replacement.

  • COMPARATIVE ANALYSIS OF THE COMPRESSIVE STRENGTH OF

    the brick aggregates concrete requires greater proportion of water than the normal gravel aggregate concrete. Use of broken over burnt bricks as coarse aggregate for structural concrete is recom-mended when natural aggregate is not easily available, high strength of concrete is not required and the bearing capacity of the soil is low.

  • Permeability prediction and pore structure feature of

    20/07/2019· Over burnt brick aggregate was used in this study as a replacement of natural stone aggregate. Brick aggregates were collected from locally available brick manufacturing industry. The sizes of brick aggregates ranged from 2.36 mm to 19 mm, consisting of five different gradation types including three single sized gradation and two dense gradation. The single sized gradations were G-1

  • (PDF) COMPARATIVE ANALYSIS OF THE COMPRESSIVE

    Trial mixes were prepared using the crushed over burnt bricks known also as brick bats as coarse aggregates only, mixture of crushed over burnt bricks and river wash gravel as well as using river washed gravel from River Benue. Cubes of concrete were prepared and tested to study the compressive strength. The result indicate that the concrete having brick bats as aggregates may be termed as

  • Compressive strength behavior of concrete by partial

    25/04/2017· Properly burnt bricks are treated ideal for construction work either in partition wall or as coarse aggregate in concrete, whereas the over-burnt bricks are usually considered as useless and are not allowed in construction works. Many researchers have been accomplished to investigate the suitability of OBBA in concrete.

  • 9 Types of Roads in civil Engineering and Construction

    Bricks and brick aggregates may be obtained from well-burnt bricks that can be used in the soiling and crushed brick aggregate in the wearing course. Well burnt or over burnt bricks may be used at some places as paving material which may or may not is covered or protected with bituminous carpet coat or surface treatment.
