Measurement and evaluation proposal of early age shrinkage of cement composites using shrinkage-cone
(IOP Publishing, 2018-07-12)
The paper deals with an experimental analysis focused on the determination and evaluation of the early age shrinkage strain using Shrinkage-Cone. The measurements were performed on the cement pastes and mortars with a ...
Experimental determination of the initial compressive strength of concrete using a rebound test hammer
(IOP Publishing, 2018-07-16)
This paper deals with rebound hammer testing of concrete in the early stage of ageing. Six types of concrete were produced for the purpose of the presented experiment and differed in the water/cement ratio and were otherwise ...
Determining reinforcement coverage using an electromagnetic rebar detector
(IOP Publishing, 2018-07-16)
Correct reinforcement is an essential part of constructing reinforced concrete structures. Errors in positioning, diameter, or coverage may result in defects, which is why it is necessary to make sure the reinforcement is ...
Early-age behaviour of cement-based self-leveling flooring compounds
(IOP Publishing, 2018-07-16)
The article deals with the cement-based flooring compounds, especially with the behaviour during the early solidification process. A touch-less laser sensor and a cone-shaped mould were used for the measurement of the ...
Ultrasonic NDT determination of initial and final setting time of cement paste
(EDP Sciences, 2020-03-05)
There are several methods for determination of the setting and early hardening in the cementitious composites. The most common method is using the Vicat apparatus. The major disadvantage of this method is that it is invasive ...
Development of the Elastic Modulus of Concrete under Different Curing Conditions
(Elsevier, 2017-07-20)
The modulus of elasticity is a property of concrete, which is known for its high variability of values. A high enough value of the modulus of elasticity is a critical requirement in complicated concrete structures and in ...
Determination of the static modulus of elasticity of cement mortars in the early stage of ageing
(EDP Sciences, 2020-03-05)
The paper deals with the influence of the composition of cementitious materials on the development of their modulus of elasticity in the early stage of ageing. The primary goal of the paper is to determine the static modulus ...
Cost-Effective High-Performance Concrete: Experimental Analysis on Shrinkage
(MDPI, 2019-08-26)
This paper focuses on the experimental determination of the shrinkage process in Self-Compacting High-Performance Concrete (SCC HPC) exposed to dry air and autogenous conditions. Special molds with dimensions of 100 mm × ...
The Acoustic Emission Parameters Obtained during Three-point Bending Test on Thermal-stressed Concrete Specimens
(Elsevier, 2017-06-02)
Fire response of concrete structural members depends on thermal, mechanical, and deformation properties of concrete. These properties vary significantly with temperature and also depend on the composition and characteristics ...
Comparison of Measurements Methods Intended to Determination of the Shrinkage Development in Polymer Cement Mortars
(Elsevier, 2017-07-20)
The paper deals with the experimental determination of the shrinkage progress of the polymer cement (PCC) mortars. The main motivation of performed measurements was to compare the results obtained from two different ...
