Mechanical, freeze-thaw, and sorptivity properties of mortars prepared with different cement types and waste marble powder

open access: yesJournal of Sustainable Construction Materials and Technologies, 2023
The cement production process contributes significantly to CO2 gas emissions and environ- mental pollution. To reduce this adverse effect, the substitution of waste marble powder as a cement additive was investigated.

The mounds of Estremoz marble waste: Between refuse and reuse [PDF]

open access: yes, 2015
Waste is commonly, considered an effect separated from the economic processes of production, construction, and consumption. This is seen both in the politics of recycling and in the legal apparatus regarding the reintegration of industrial wastelands, in the aftermath cessation of the exploitation.

Two‐dimensional guillotine cutting problem for large objects with non‐rectangular shapes

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract In this paper, we address the two‐dimensional single large object placement problem with guillotine cutting constraints, focusing on non‐rectangular shapes. We consider objects with circular or convex polygonal geometries and study a variant that includes defective regions from which no items can be extracted. Rectangular items are cut using a

Valorization of marble waste in the manufacture of concrete

open access: yesIOP Conference Series: Materials Science and Engineering, 2018
The building materials manufacturing industry generates a lot of waste and their landfill has many problems (including the place occupied by the storage sites, the importance of the costs and the impact on the environment). This industry does not pose problems only at the end of the life cycle of these materials.

Adaptation to extreme environments: A review of Antarctic fish physiology

open access: yesJournal of Fish Biology, EarlyView.
Abstract Having evolved in the chronically cold and thermally stable waters of the Southern Ocean (SO) for millions of years, Antarctic fish possess a suite of physiological specializations that enable them to survive at temperatures near the freezing point of seawater. Adaptations include the evolution of antifreeze proteins, modifications of membrane

Remembering Independence, Debating the Nation: Ghana's National Days

open access: yesNations and Nationalism, EarlyView.
ABSTRACT In Ghana, Independence Day is the most important national day and has been annually observed since the attainment of independence in 1957. Additional national days that various military governments introduced to commemorate their ascension to power have been rather short‐lived. Other holidays like Republic Day or Founder's Day have been longer

Analysis of the suitability of marble waste for beach nourishment

open access: yesMarine Georesources & Geotechnology, 2022
Marble waste, as a subproduct of the exploitation of marble quarries, could be reused as a replacement for the scarce sand sediment supply for beach nourishment. This work studied the suitability of 4 different types of marble (Bateig, Ivory Cream, Imperial Brown and Niwala).

Remineralisation of Reverse Osmosis (RO) Water Using Synthetic Aragonite

open access: yesWater and Environment Journal, EarlyView.
ABSTRACT Reverse osmosis (RO) treated water often requires remineralisation to restore Ca2+ ions, hardness and alkalinity, particularly for potable water. This study compares the dissolution characteristics of two forms of calcium carbonate, aragonite and calcite.
