Concrete is a highly consumed material in construction field due to its advantages because of this the natural resources are depleting day by at an alarming rate and there immediate need for finding alternate materials concrete. So, my study M30 grade concrete adopted cement was replaced with Egg Shell powder different percentages 5%, 10%, 15% 20% M-Sand constant percentage 40%. casted, cured t...

Recently, background independent open-string field theory has been formally defined in the space of all two-dimensional world-sheet theories. In this paper, to make the construction more concrete, I compute the action for an off-shell tachyon field of a certain simple type. From the computation it emerges that, although the string field action does not coincide with the world-sheet (matter) par...

By regarding gravity as the convolution of left and right Yang-Mills theories together with a spectator scalar field in the biadjoint representation, we derive in linearized approximation, the gravitational symmetries of general covariance, p-form gauge invariance, local Lorentz invariance, and local supersymmetry from the flat space Yang-Mills symmetries of local gauge invariance and global su...

P. Bigoš, J. Kuľka, M. Mantič, M. Kopas , Faculty of Mechanical Engineering, Technical University of Košice, Slovakia This paper describes measuring of time behaviour specified for local stress increments on the blast furnace shell that were performed using strain gauge sensors. These results are compared with values obtained by means of the second specific measuring method. There is also prese...

This paper will examine the relationship between artistic intentions and structural constraints of materiality and form related to the work of Donald Judd’s ten concrete buildings at the Chinati Foundation in Marfa, Texas. Although the project was designed to be an ambitious structural thin shell concrete buildings, only minimal documentation of the project was produced, and only portions of th...

The construction industry generates a considerable amount of waste. Faced with this undesirable situation, the ready-mix concrete sector, in particular, has invested energy and resources into reusing its own waste in its production process as it works towards the goal of more sustainable construction. This study examines the feasibility of incorporating two types of concrete waste, which curren...

The susceptibility of structural concrete to early-age cracking depends on material composition, methods of processing, structural boundary conditions, and a variety of environmental factors. Computational modeling offers a means for identifying primary factors and strategies for reducing cracking potential. Herein, lattice models are shown to be adept at simulating the thermal-hygral-mechanica...
