  • profit estimation models of industrial and Engineering Brick manufacturing using uasb reactor sludge
    Journal of Advances in Environmental Health Research, 2018
    Co-Authors: Syeda Azeem Unnisa, Malek Hassanpour
    Abstract:

    According to a recent report by the Iranian industrial organization, over 1700 Industrial and Engineering Brick Manufacturing (IEBM) industries are currently running in Iran, using the same method in common use worldwide. The present research study used a combination of a literature review, existing research reports, and a model of assessment among the four main kinds of IEBM industries to estimate the profit of IEBM using Wastewater Treatment Plant (WWTP) sludge as a model. Paying attention to differences in Brick manufacturing practices among the many published papers, we summarized the available standard procedures and methods. Both the paired test and t-test analyses revealed a significant difference among parameters such as initial feed, employees, power, water, fuel, and land (pvalue ≤ 0.001) for the four main types of IEBM industries in Iran. The evaluation identified a priority hierarchy among factors: employees> land > initial feed > water > power > fuel. Therefore, automation in this industry is recommended. Next, two models were developed to estimate the profit of a WWTP and Four Main Brick Manufacturing Industries (FMBMI) using released sludge from the WWTP.

  • Evaluation of solidified and stabilized shipyard abrasive blasting waste as construction material / Salmaliza Salleh
    2018
    Co-Authors: Salmaliza Salleh
    Abstract:

    Tons of abrasive blasting wastes (ABW) are produced each year from the removal of old paint from the ships. The abrasives contain heavy metals which are considered hazardous by the Toxicity Characteristic (TC) criteria. This research describes an investigation of cement-based solidification and stabilization (S/S) of the spent abrasives from ship repair, which is mainly spent copper slag. ABW which are mixed with Ordinary Portland cement (OPC) ranging from ratio of 0 to 1.5 by weight of cement were tested for crushed block leachability and compressive strength. The water-to-cement ratio of the mixes was set at 0.35 to 0.5. The results indicated that the leaching of selected heavy metal ions from the cement matrix was low and did not exceed the United States Environmental Protection Agency (US EPA) and Malaysian Department of Environment (DOE) Regulation Guidelines. However, addition of abrasive blasting waste to cement increased the initial setting times, which retards the process of hardening of the cement matrix. The strength of the S/S abrasives was generally lower than the control cement paste. Optimum strength achieved when the ratio of C/ABW is 1.5 with water-to-cement ratio of 0.35. In the next stage of study, sand was added in the cement-ABW matrix to develop Bricks for construction purpose. The strength of the C/ABW Bricks was generally higher than the control and conventional sand-cement Bricks. The optimum strength achieved when 20% of sand weight was replaced by the ABW with water-to-cement ratio of 0.35. The C/ABW Brick may be classified as Engineering Brick Type B due to its high strength and low water absorption property. In the later stage, coarse aggregates were added in the C/ABW Bricks design matrix to test the possibility of producing concrete with solidified and stabilized Abrasive Blasting Waste as fine aggregates. The results showed that concrete with ABW has reached compressive strength of 79 MPa at 28th day which is classified as high strength concrete

  • prestress loss of post tensioned clay diaphragm and fin Brickwork
    1994
    Co-Authors: Siti Hamisab Tapsir
    Abstract:

    Unlike calcium silicate and concrete block masonry which undergo shrinkage with time, clay Brickwork has been known to expand instead. Expansion of Brick units in prestressed masonry will cause an increase in the prestressing force instead of prestress loss. However, not all clay Brickwork expand with time; higher strength clay units tend to undergo shrinkage with time. The main objective of this paper is to present experimental data obtained for prestress loss in post-tensioned high strength clay diaphragm and fin Brickwork. The main objective of this paper is to present experimental data obtained for prestress loss in posttensioned high strength clay diaphragm and fin Brickwork. The Brickwork were built from clmisB clay Engineering Brick with compressive strength of 103 MPa with designation (ii) mortar. The tests which involve monitoring prestress loss, creep and shrinkage of clay sections were carried out over a period of 120 days. Usiog the 120-day experimental data, the predicted long-term prestress loss is 20%
