Experimental work was carried out to investigate the effect of fire flame (high temperature) on specimens one way slabs using Self Compacted Concrete (SCC). By furnace manufactured for this purpose, twenty reinforced concrete slab were exposed direct flame. All have same dimensions. The cooled in two types, gradually by left them air and suddenly water. After that tested under point loads, stud...

Analyzing the working conditions of a dam using safety monitoring indices (SMIs) is relatively intuitive and effective method for evaluation. Therefore, reasonable accurate determining SMIs vital importance assessment. However, current methods dams, especially roller-compacted concrete (RCC) have many shortcomings, such as ignoring construction process dam, coupling effect among multiple physic...

To reduce CO2 emissions from the building industry, one option is to replace cement in specific applications with alternative binders. The Carbstone technology based on reaction of calcium- and magnesium-containing minerals form carbonate Mixes carbon steel slag stainless-steel slag, tailored particle size distributions, were compacted a vibro-press subsequently carbonated an autoclave produce ...

To date, there is no data on the change in strength of hyper - compacted concrete. The conducted field observations summarize a long-term period and allow us to draw number conclusions. As shown by numerous studies, nature development concrete over time depends mainly type cement, composition mixture, temperature humidity conditions hardening, also many other factors. Obtaining highly efficient...

BACKGROUND Left ventricular non-compaction (LVNC) is a recently recognized rare disorder. Magnetic resonance imaging (MRI) may help to clarify the uncertainties related to this genetic cardiomyopathy. Despite the fact that many articles have been published concerning the use of MRI in the study of LVNC, there is a lack of data describing the disease in the North African population. The aim of o...

This paper presents experimental and analytical work of which the main objective was to support introduction a new technology for production sewer pipes. In this technology, pipes produced consist two differently parts. The direct part uses conventional vibro press compacted concrete. curved part, on other hand, self-compacting concrete is used. cooperating company, Prefa Brno a.s., defined pos...

A limited number of studies are available on the impact polymer modified concrete corrosion effect Reinforced Concrete (RC) structures, such as bridges exposed to maritime environments or de-icing salts. The aim this research was analyse influence polymers mechanical and durability properties concrete. Seven types recyclable thermoplastic PCL, Polymorph, LDPE/EVA granular, powder, GPE, N-228 TP...

In this paper we present novel correlation analyses methods to analyze the compacted test sets. In spatial correlation, we identified strong correlation chains, while in the temporal domain, correlating a segment of the test set with the entire sequence discovered periodicities in the compacted test set sequence. These suggest the potential of a new way for generating test sequences. We report ...
