“…Carbonation is also crucial in the setting of traditional lime mortars that have been used as a building material since the advent of pyrotechnology ca. 12000 years ago [10][11][12][13][14][15][16][17][18][19][20][21][22]. It is also of importance in the long-term durability of concrete, where Ca(OH) 2 , i.e., portlandite, is one of the major phases formed during cement hydration [23][24][25][26].…”

Phase and morphology evolution of CaCO 3 precipitated during carbonation of lime pastes via the reaction Ca(OH) 2 ? CO 2 ? CaCO 3 ? H 2 O has been investigated under different conditions (pCO 2 & 10 -3.5 atm at 60 % RH and 93 % RH; pCO 2 = 1 atm at 93 % RH) using XRD, FTIR, TGA, and SEM. Simulations of the pore solution chemistry for different stages and conditions of carbonation were performed using the PHREEQC code to investigate the evolution of the chemistry of the system.

“…Papadakis et al 1991;Johanneson and Utgenannt 2001;Short et al 2001;Van Balen 2005). More recently, research has also focused on accelerated carbonation treatment of cement-bound waste to promote the stabilization degree and improve the leaching behaviour of the treated material (Lange et al 1996;Bin-Shafique et al 1998;Van Gerven et al 2006).…”

The increasing volumes of municipal solid waste produced worldwide are encouraging the development of processes to reduce the environmental impact of this waste stream. Combustion technology can facilitate volume reduction of up to 90%, with the inorganic contaminants being captured in furnace bottom ash, and fly ash/APC residues. The disposal or reuse of these residues is however governed by the potential release of constituent contaminants into the environment. Accelerated carbonation has been shown to have a potential for improving the chemical stability and leaching behaviour of both bottom ash and fly ash/APC residues. However, the efficacy of carbonation depends on whether the method of gas application is direct or indirect. Also important are the mineralogy, chemistry and physical properties of the fresh ash, the carbonation reaction conditions such as temperature, contact time, CO(2) partial pressure and relative humidity. This paper reviews the main issues pertaining to the application of accelerated carbonation to municipal waste combustion residues to elucidate the potential benefits on the stabilization of such residues and for reducing CO(2) emissions. In particular, the modification of ash properties that occur upon carbonation and the CO(2) sequestration potential possible under different conditions are discussed. Although accelerated carbonation is a developing technology, it could be introduced in new incinerator facilities as a "finishing step" for both ash treatment and reduction of CO(2) emissions.

BerichteLooking around us, we notice the durability of masonry structures. A well-built masonry structure provides a long term sustainable solution by virtue of its durability, adaptability and maintainability. However, building practice has changed in the last 50 years: building speed and technology, rather than quality and durability, have become the major drivers for the mainstream construction industry. The common market created by the EU has led to a unified market requiring common definitions. Unified product standards have been developed, and structural engineering guidelines written, to ensure a market where products can freely circulate. In the sector concerned with restoration of cultural heritage, scientists and conservators have been working to develop products that match original materials and performance, many of which have been standing for hundreds of years. In recent years, sustainability and durability have increasingly driven the mainstream construction industry. In current masonry practice, several issues have been observed: masonry has become increasingly brittle, stress sensitive and increasingly slender, therefore calling into question its traditional image of solid, durable and sustainable building material. Lesson for modern masonry practice can be found from current studies of traditional work and materials. The complex stress state in the mortar explains the ductile behaviour of masonry with low strength lime based mortars. The lower strength and stiffness of lime mortars is beneficial to traditional walls. Inspired by these observations, the article discusses the background of this evolution and searches for a future of durable, sustainable masonry. Mauerwerk
