Abstract The Spanish economy was the most hit by Great Recession. It suffered a greater decrease in gross domestic product (GDP) (affecting especially internal demand). However, it increase exports (the so-called “miracle”). Particularly, SMEs incorporation into has been spectacular since 2008. Further, this coincided with huge unemployment. Therefore, our main objective is to investigate moder...

Concrete is the most used building material in world, due to its high compressive strength and durability. Those properties are measured assessed fresh hardened states of concrete, with standard methods which time cost consuming. In present study, slump concrete has been predicted using Artificial Neural Network (ANN), constructed different input parameters involving mix design (i.e. coarse &am...

Abstract In order to decrease the fitting deviation between rheometrical measurements and empirical parameters using slump test, this paper proposes a new analytical method evaluate high yield stress of materials (cement pastes).In doing so, an experimental study was performed for measuring characteristics by cylindrical mold with different water binder ratios (w/b) aiming increase stress. Para...

The use of waste rock as an aggregate in mining backfill is environmentally friendly and cost-saving. slurry flow property varies with the change aggregate, binder content, solid concentration, additives. a pipeline governed by its properties, which makes it crucial to study properties their effects. One example fly ash-waste mixed Jinchuan Nickel, China. Tests on slump, slump flow, mortar cons...

The present study focused on developing Alkali Activated Fine Aggregate (AAFA) by palletization method. AAFA was manufactured using Ground Granulated Blast Furnace Slag (GGBS) and alkali activator solution at ambient conditions. Sodium hydroxide of six molarity sodium silicate to ratio 2.5 used. AACA's properties are similar Natural except for flakiness elongation index. water absorption Abrasi...

The slump test is a tool to assess the mechanosensitivity of the neuromeningeal structures within the vertebral canal. While some studies have investigated the reliability of aspects of this test within the same day, few have assessed the reliability across days. Therefore, the purpose of this pilot study was to investigate reliability when measuring active knee extension range of motion (AROM)...

In this study, first, different mix design of four types of Self-Compacting Concrete (SCC), 1. SCC consisted of only nanosilica, 2. SCC included only microsilica, 3. SCC consisted of both microsilica and nanosilica and 4. SCC without microsilica and nanosilica called as control mix, were casted and tested to find out the values of the Slump Flow, L-Box and 7 and 28 days compressive strength. Th...

Recent scientific concerns to achieve sustainability in construction have suggested the implementation of using recycled aggregate in concrete because it has the potential to reduce the demand for extraction of natural raw materials and decrease the volume of wastes landfilled. In this respect, this study aims to investigate the suitability of using ceramic tile (CT) and ceramic sanitary (CS) w...
