“…3. Volumetric shrinkage of each mixture was calculated according to (1); where S v is volumetric shrinkage, V 1 is initial volume (70 3 mm 3 ) and V 2 is final volume at the measuring date [16]. Average of the shrinkage values of three replicates were calculated as the volumetric shrinkage of each mixture.…”

“…Bricks, roof tiles, lightweight aggregates, cement, concrete and geopolymers were the products that experimented to incorporate DWTS with raw materials [2], [13]- [15]. At the end of each study it was concluded as incorporating of DWTS with products is not totally success and the shrinkage of DWTS was identified as the major issue [16].…”

“…Shrinkage is one of the basic properties of DWTS which create negative impact when used as a raw material in production process. Shrinkage can be measured as volumetric shrinkage and observational shrinkage [16]. Observational shrinkage is considered as the cracks observed after drying and the volumetric shrinkage is considered as the volume reduction after drying.…”

“…Historical evidence shows that natural fibers, binders and additives were used to avoid shrinkage of clay based productions and applications [17]- [19]. As the DWTS is categorized under clay; according to the USCS soil classification, shrinkage can be overcome through historical practices before used as a raw material [2], [16].…”

Water is one of the basic human needs and the country has the main responsibility to confirm their citizens' provision to safe water. Most of the countries in the world supply treated water to the country through water treatment plants. In drinking water treatment plants, solid sludge is generated at the end of the water treatment process as a waste product which is now becoming a global problem. In previous studies, shrinkage was identified as the major problem of drinking water treatment sludge (DWTS), accrued when use it as a raw material. This study was conducted to analyze the performance of both chemical and physical additives, to identify the possible additive to overcome the shrinkage of DWTS. In the study eight mixtures were prepared by adding Styrene Acrylic Binder as the chemical additive and sand and sugarcane fiber as physical additives separately and together and volumetric shrinkage of each mix was measured weekly. According to the results of this study it was concluded as, shrinkage of DWTS can be reduced by adding physical additives. Physical additives perform more effectively than chemical additives in the reduction of shrinkage of DWTS. Further studies are required to find the optimum mixing ratios of physical additives to optimize the performances.Index Terms-Chemical additives, drinking water treatment sludge (DWTS), physical additives, shrinkage.

“…Existing for thousands of years, using earth as a construction material is not uncommon and has been fundamental for buildings around the world (Emiroğlu, Yalama and Erdoğdu, 2015) (Minke, 2006). These techniques have been left in the past in favour for more 'fashionable' and fossil fuel intensive materials such as steel and concrete.…”

Bio-fibres and earth as a building material have been used for thousands of years and can be utilised due to their relative abundancy around the globe. The aim of this work is to combine these materials in order to give potential for a new, sustainably sourced, non-load bearing hygric buffering panel for indoor thermal management with bio-fibres commercialised in UK. Currently, there is limited knowledge specifically as to how bio-fibres and earth combine in order to enhance their inherent characteristics. This uses two differing mix designs and 3 differing bio-fibres (Wool 1, Wool 2 and Saw Mill Residue). Earth was utilised by using locally sourced material from Liverpool (NW England). Prismatic, 0.1m 2 x 0.1m 2 and 40mm disc samples were cast and samples were exposed to cyclical step changes in relative humidity at 75% for 8 hours and 53% for 16 hours at 23 o C, in order to mimic a UK household occupancy. Results demonstrate that an optimised mix lead to at least 30% improvement of properties if Saw Mill Residue (SMR) is added. In comparison to a plain earth mortar, the addition of SMR reduces density, porosity and increases moisture buffering.

Indoor air quality is important for comfort and health of buildings inhabitants. The use of environmentally friendly building materials is also very important for sustainable and green buildings. In the present study, mechanical characteristics of five mortars were comparably analyzed: two unstabilized earth mortars, one earth-air lime mortar, one cement mortar and other gypsum mortar. The earthen plasters are nowadays commonly applied unpainted. The gypsum plaster system is composed by the base mortar and a finishing layer; it can be applied unpainted or painted. The cement plaster is generally finished with a paint system. Therefore, the adsorption and desorption capacities were assessed for all the plasters and the influence of the paint system was evaluated for the cement and gypsum plasters. Results show that the earth mortar stabilized with air lime presents lower mechanical strength, in comparison to all other mortars, and lower adsorption capacity, similar to the gypsum system. The unstabilized earth plasters present high adsorption capacity, in comparison to the cement and gypsum plasters. The paint system does not have significant influence on the adsorption capacity of the gypsum plaster but reduced that capacity on the cement plaster. These results demonstrate the important contribution that unstabilized earth plasters may provide as passive indoor hygrothermal buffers, in comparison to other plasters.
