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 ...
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 ...
Experimental Analysis on Shrinkage and Swelling in Ordinary Concrete
(Hindawi Publishing Corporation, 2017-05-22)
The paper deals with the experimental determination of shrinkage development during concrete ageing. Three concrete mixtures were made. They differed in the amount of cement in the fresh mixture, 300, 350, and 400kg/m3. ...
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 ...
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 ...
Destructive and non-destructive assessment of the frost resistance of concrete with different aggregate
(IOP Publishing, 2018-07-12)
The paper focuses on determining the frost resistance of concrete using selected destructive and non-destructive test methods. The experiment was performed with four specially made concretes, which differed only in the ...
Influence of the gripping fixture on the modified compact tension test results: evaluation of the experiments on cylindrical concrete specimens
(VŠB-TUO, 2015-12-18)
The modified compact tension test (MCT) might become in the future a stable test
configuration for the evaluation of fracture-mechanics parameters or also for description of fatigue
behavior of composites materials such ...
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 ...
Evaluation of Shrinkage, Mass Changes and Fracture Properties of Fine-aggregate Cement-based Composites during Ageing
(Elsevier, 2017-06-02)
The paper deals with the experimental determination of relative length changes development during cement based composite ageing. Special moulds with the dimensions 100 × 60 × 1000 mm were used for the measurements. These ...
Shrinkage, weight loss and fracture parameters of selected polymer-modified cement mortars during ageing
(VŠB – Technical University of Ostrava, 2017-06-01)
Results of pilot experiments focused on monitoring of shrinkage, weight loss and mechanical fracture properties of two selected polymer-modified cement mortars (PCM) during their aging are presented in the paper. Comparison ...
