Application of Ceramic Powder as Supplementary Cementitious Material in Lime Plasters

In this paper, the properties of plasters based on lime – brick powder binder of varying composition (ceramics content from 0 to 80 %) are studied. The plasters are prepared with a constant water amount. The pore size distribution is thus influenced in a positive way; the total porosity increases with the ceramics content but the volume of capillary pores is reduced. It results in lower water vapor diffusion resistance factor while the apparent moisture diffusivity coefficient increases just moderately. The influence of ceramic on strength of plasters is not found very important. The thermal conductivity of plasters containing ceramics is lower than those with the pure lime what is again in agreement with the pore size distribution. It can be concluded that fine brick powder can be used as pozzolanic admixture in lime based plasters with a positive influence on its functional parameters

Thermophysical and mechanical properties of fiber‐reinforced composite material subjected to high temperatures

The bulk density, open porosity, matrix density, tensile strength, bending strength, thermal diffusivity, specific heat capacity, thermal conductivity and linear thermal expansion coefficient of high‐density glass fiber reinforced cement composite are determined as functions of temperature up to 1000 °C. The basic physical parameters and mechanical parameters are found to exhibit the most important changes between the reference state and 600 °C pre‐heating where the increase of porosity is as high as 40% and both the tensile strength and bending strength decrease to about one third of their original values. The measured dependences of thermal diffusivity and thermal conductivity on temperature indicate that the heat transfer in the studied material is accelerated once temperature achieves 500–600 °C but the change in heat storage expressed by the specific heat capacity is less important. The linear thermal expansion coefficient is not found to be affected by high temperatures in a negative way; it is either lower or comparable to its low‐temperature values. Santrauka Tiriama, kaip kinta tankiojo stiklo pluoštu armuoto cementinio kompozito tankis, atvirasis poringumas, matricinis tankis, tempiamasis bei lenkiamasis stipris, terminis laidumas, savitasis šilumos imlumas, savitasis šilumos laidumas ir tiesinis terminio pletimosi koeficientas, kai šia medžiaga veikia temperatūra, kylanti iki 1000 °C. Rasta, kad pagrindiniai fiziniai ir mechaniniai parametrai daugiausia keičiasi temperatūrai kylant nuo pradines iki 600 °C. Šioje temperatūros kilimo atkarpoje poringumas išaugo iki 40 %, o tempiamasis ir lenkiamasis stipriai sumažejo maždaug trečdaliu, palyginti su pradinemis reikšmemis. Išmatuotoji terminio laidumo ir savitojo šilumos laidumo priklausomybe nuo temperatūros rodo, kad šilumos perdavimas tiriamoje medžiagoje pagreiteja temperatūrai pasiekus 500–600 °C, tačiau šilumos kaupimas, išreikštas savituoju šilumos imlumu, yra ne toks svarbus. Nenustatyta, kad tiesinis terminio pletimosi koeficientas būtu neigiamai veikiamas aukštos temperatūros. Šio koeficiento reikšmes yra mažesnes arba maždaug lygios reikšmems, išmatuotoms žemoje temperatūroje.

Characterization of fracture patterns and hygric properties for moisture flow modelling in cracked concrete

International audienceSeveral years after their installation, building materials such as concrete present signs of ageing in the form of fractures covering a wide range of sizes, from microscopic to macroscopic cracks. All sizes of fractures can have a strong influence on heat and moisture flow in the building envelope, but their distribution is difficult to predict due to the variety of environmental factors which cause them. This paper aims at applying experimental non-destructive techniques for the observation of fracture patterns and of fluid flow in fractures, in order to provide this data to models for fluid transfer in fractured porous media. Digital image correlation was performed during the fracturing of concrete samples, in which moisture uptake was then monitored using X-ray radiography. Finite-element simulations were then performed based on the measurements of the fracture patterns, in order to recreate the measured moisture concentration profiles. Digital image correlation was found suitable as a mean to obtain a complete mapping of the deformations at the surface of the samples, and a first step was made towards the use of non-destructive fracture characterization for the purpose of moisture transfer modelling

Strength and durability of composite concretes using municipal wastes

The influence of different types of polyethylene (PE) substitutions as partial aggregate replacement of micro-steel fiber reinforced self-consolidating concrete (SCC) incorporating incinerator fly ash was investigated. The study focuses on the workability and hardened properties including mechanical, permeability properties, sulfate resistance and microstructure. Regardless of the polyethylene type, PE substitutions slightly decreased the compressive and flexural strength of SSC initially, however, the difference was compensated at later ages. SEM analysis of the interfacial transition zone showed that there was chemical interaction between PE and the matrix. Although PE substitutions increased the permeable porosity and sorptivity, it significantly improved the sulfate resistance of SCC. The influence of PE shape and size on workability and strength was found to be more important than its type. When considering the disposal of PE wastes and saving embodied energy, consuming recycled PE as partial aggregate replacement was more advantageous over virgin PE aggregate replaced concrete
