As Raw Materials

Abstract
Marble waste, in the form of sludge obtained from the marble cutting industry,
was incorporated in the mixture formulations of concrete block. The possibility
of using marble sludge powders (MSPs) as a substitute for limestone was
investigated over a three year period. The production of cement block from
sludge was standardised in terms of process and content. Interpretation of the
results have shown that appropriate incorporation of MSP can result in
favourable characteristics in terms of compression strength 9 N/nm2 at 28 days,
and water absorption (7%), anticipating a complimentary usage of sludge as a
by-product instead of being waste.
Keywords: eco-construction blocks, marble sludge powder, cement, sustainability, environment, waste re-use.
1 Introduction
Nowadays, the growing consumption of available natural resources as raw
materials in industry leads to their decreasing quantity, as well as quality, in
nature. In addition, the marble cutting industry generates a high volume of
wastes.
The most important issue that forms the basis of this project is that the
amount of construction and demolition waste in landfill sites and municipalities
side roads is expected to increase in the near future at international levels.
Several research projects are being conducted by incorporation of these waste
materials to reduce their environmental impact, especially after being air dried.
Keywords
eco-construction blocks, marble sludge powder, cement, sustainability, environment, waste re-use.
