“…The main advantage of MCT test is a round shape of the specimen that makes it appropriate for testing cement based composites. Due to its shape, it is easy to prepare specimen both ways: by cutting them of the drilled core in case of constructions which are already being used [6][7][8]15,] as well as in forms from the fresh concrete mixture [24]. The geometry of the specimen is shown in Fig.…”

ABSTRACT. The evaluation of fracture mechanics parameters of materials has become very important part of considering the condition of older constructions as well as properties of newly developed materials. This contribution focuses on a numerical simulation and a calculation of fracture mechanical properties of modified compact tension test configuration. It is possible to prepare the specimens used for this test very easily from a drilled core or from specimens used for cylindrical compression test. The focus of contribution is to compare selected outputs from numerical solution of 2D (plane strain conditions) with 3D models. Particularly, the determination of the influence of 2D and 3D model on the calibration curves for selected fracture mechanics parameters is of interest. Finite element software ANSYS was used for the numerical analysis. KEYWORDS. Stress Intensity

“…For testing the number of samples carried out in the study of 120 cube samples (150 mm x 150 mm x 150 mm), the percentage of husk ash was 0%; 5%; 10% and 15%, the number of 24 cube samples by reviewing the compressive strength of 28 days. The purpose of experimental measurements is to determine the effect of the number of core samples on the quality of the data obtained [21]. The number of samples can be seen in Table 6.…”

Abstract. Concrete material made from natural waste was developed to balance the use of concrete materials resulting from natural exploration with an impact on environmental damage, rice husk is a waste material from rice mills and contains reactive silica and has the benefit of reducing energy consumption in cement production. Laboratory test method in the form of testing the compressive characteristics used standard cube concrete 150 mm x 150 mm x 150 mm with a total sample of 24 samples. The effect of concrete strength on the amount of cement replacement is 0%; 5%; 10% ; and 15% which could be compared with concrete without using husk ash. The compressive strength obtained in terms of the age of the concrete is 28 days. The mechanical properties of husk ash at the age of 28 days gave optimal compressive strength results with the addition of 5% husk ash.

Abstract-This article is focused on problematic of interaction between foundation structure and subsoil. This phenomenon is observed through the experimental measurements on the large scale models and these experiments are realized on testing device located at the Faculty of Civil Engineering, VSB-Technical University of Ostrava. In this contribution are presented experimental results of static load test implemented on the concrete industrial floor model.
