Ceramic bricks based on low-melting clay and ferro-dust from self-disintegrating, low-carbon, ferrochrome slags, graded M100 to M175, respectively, were obtained in the temperature range 950 – 1100°C. The highest grades are fired at temperatures 1050 1100°C, M150 which can be used as earthquake-resistant. Studies have shown that hematite, wollastonite, diopside a liquid phase appear brick firin...

In this work we solve a special case of the problem of building an n-dimensional parallelepiped using a given set of n-dimensional parallelepipeds. Consider the identity x = xHx 1L Hx 2L + 3 xHx 1L + x. For sufficiently large x, we associate with x3 a cube with edges of size x, with x Hx 1L Hx 2L a parallelepiped with edges x, x 1, x 2, with 3 x Hx 1L three parallelepipeds of edges x, x 1, 1, a...

A brick is a 3-connected graph such that the graph obtained from it by deleting any two distinct vertices has a perfect matching. A brick is minimal if for every edge e the deletion of e results in a graph that is not a brick. We prove a generation theorem for minimal bricks and two corollaries: (1) for n ≥ 5, every minimal brick on 2n vertices has at most 5n − 7 edges, and (2) every minimal br...

According to the masonry standard the compressive strength is basically dependent on factors such as the mortar strength and the relative values of unit and mortar strength. However interlocking brick has none or less use of mortar. Therefore there is a need to investigate the behavior of masonry walls using interlocking bricks. In this study a series of tests have been conducted; physical prop...

Introduction: The vanadium-titanium iron ore tailings (VTIOTs) has a significant amount of discharge, and serious pollution, which makes it difficult to use directly as resources resource. Methods: High-strength fired water permeable brick (HSFWPB) was prepared using VTIOTs the main raw material. orthogonal test, X-ray diffraction analysis (XRD), scanning electron microscope (SEM), energy dispe...

considering the pivotal role that job plays in people’s lives, it can be argued that getting fired may have many consequences for the individual and his or her family and friends. however, there is little understanding of this experience. using giorgi and giorgi’s phenomenological method, this study aims to describe the meaning of this experience. the sample includes 8 people who have recently ...

A feasibility study on Usumacinta River sediment-based bricks for resilient housing adapted to both climate change and seismic risks is performed laterally loaded reduced-scale walls. Mortar formulations with different volume ratios of lime sand (2/1, 1/2, 1/4, 1/6) are prepared while types thoroughly investigated, manufactured strength characterized. Commercial fired as reference completed the...

There have been many attempts to understand the statistical origin of black-hole entropy. Among them, entanglement entropy and the brick wall model are strong candidates. In this paper we show a relation between entanglement entropy and the brick wall model: the brick wall model seeks the maximal value of the entanglement entropy. In other words, the entanglement approach reduces to the brick w...
