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. ...
Comprehensive Testing Techniques for the Measurement of Shrinkage and Structural Changes of Fine-Grained Cement-Based Composites during Ageing
(Hindawi Publishing Corporation, 2017-01-15)
The paper deals with an experimental analysis focusing on the utilization of a specific measurement technique for determining the development of shrinkage and for monitoring structural changes in fine-grained cement-based ...
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 ...
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 ...
Fracture parameters of fine-grained composites based on the alkali-activated slag
(IOP Publishing, 2018-07-12)
The paper deals with the experimental determination of fracture parameters of the composites based on the alkali-activated slag (AAS) at different ages. The main aim of the experimental investigation was to verify the ...
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 ...
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 ...
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 ...
