This study demonstrates the feasibility of using a simple method to measure the resonant fundamental frequency for determining the MOE (dynamic Young’s modulus) of lime and cement mortars. The procedure follows the instructions stated in the UNE-EN ISO 12680-1 standard for refractory products although in this study the instructions are applied to standardized RILEM 4x4x16 cm test samples made o...

The addition of 2 and 5 wt% piassava fiber, a natural lignocellulosic fiber extracted from Brazilian palm tree botanically named Attallea funifera, into cement-based matrix composites was investigated. Both alkali-treated fibers by NaOH non-treated were embedded in Portland cement, lime, sand to fabricate mortars intended for civil construction. non-aged fresh tested paste consistency, water re...

The orientation of steel fibers in magnetically driven concrete and magnetically driven mortar was experimentally studied in this paper using a magnetic method. In the magnetically driven concrete, a steel slag was used to replace the coarse aggregate. In the magnetically driven mortar, steel slag and iron sand were used to replace the fine aggregate. A device was established to provide the mag...

Microbial induced carbonate precipitation (MICP) is a new geotechnical engineering technology used to strengthen soils and other materials. Although it considered be environmentally friendly, there lack of quantitative data objective evaluation support conclusions about its environmental impact. In this paper, the energy consumption carbon emissions MICP are quantitatively analyzed by using lif...

The effects of aggregate characteristics on flow ability of mortar mixtures were investigated. Two types, five single sizes, and three gradations of fine aggregate were considered. Uncompacted voids of the aggregates were measured. Flow properties of 166 mortar batches made with the aggregates, together with different sand-to-cement ratios (s/c) and water-to-cement ratios (w/c), were evaluated ...

Abstract This paper focuses on the in-plane behaviour of rubble stone masonry with lime mortar strengthened different solutions. For that, 12 wall specimens, construction features typical ancient historic buildings Southern Portugal and Mediterranean countries, were subjected to quasi-static cyclic tests. The applied retrofit solutions are specific for buildings, such as injection FRCM systems,...

The construction and demolition waste can be used as an alternative with a lower environmental impact compared to the use of natural aggregates in concrete mortar manufacture. In this work, it has been performed analysis lime cement properties made ceramic recycled reinforced three types fibers: glass, basalt carbon. An experimental campaign carried out which includes chemical physical characte...

Lymphocyte membrane rafts contain molecules critical for immunoreceptor signaling. Here, we report identification of a new raft-associated adaptor protein LIME (Lck-interacting molecule) expressed predominantly in T lymphocytes. LIME becomes tyrosine phosphorylated after cross-linking of the CD4 or CD8 coreceptors. Phospho-LIME associates with the Src family kinase Lck and its negative regulato...

Due to greenhouse gas emissions, the production of cement clinker is considered unsustainable and many attempts are being made replace with alternative materials sourced from agriculture, industry other urban practices, such as construction demolition works. The aim this paper analyze effects substitution by locally available waste in Serbia, fly ash (FA), blast furnace granulated slag (BFGS) w...

A lime kiln is used to convert lime mud into lime for reuse in the causticizing plant of the kraft recovery process. Many of the problems encountered in lime kiln operations can be related to kiln chemistry, including TRS and SO2 emissions, dusting, ringing and refractory brick thinning. Understanding the composition and thermal behaviour of lime mud and the major chemical reactions involved is...
