Propuesta de concreto de baja permeabilidad con adición de polvo de ladrillo de arcilla para la construcción de viviendas en ambientes marinos, Cerro Azul Cañete

Castillo Gonzales, Mayela Danixa, Hernández Muñaqui, Kevin Aldo 15 January 2020 (has links)
El deterioro de las estructuras de concreto debido al ataque de agentes externos, es una de las problemáticas con más énfasis en el rubro de la construcción, ya que afecta directamente las propiedades de la infraestructura, dando como resultado la reducción de vida útil. Por otro lado, tenemos el incremento de construcciones cerca al litoral marítimo, sin embargo, surge la problemática de presencia de eflorescencia, desprendimiento, corrosión o manchas en el concreto, por el ataque de sulfatos presente en el agua de mar, en el suelo, y en la humedad. A lo largo de los años se ha propuestos productos como adiciones en la composición del cemento o productos no permeables para aplicar al concreto, con el fin de minimizar el impacto. Para la presente investigación se estudia la efectividad del polvo de ladrillo, como reemplazo parcial del cemento, mediante los ensayos de resistencia a la compresión, trabajabilidad en estado fresco, volumen de contenido de vacíos y permeabilidad. Se realizó pruebas con cuatro diferentes proporciones de reemplazo como es 5%, 15%, 25% y 30%, para una resistencia de f´c 300 kg/cm2. De acuerdo a los resultados, se concluyó que la muestra con reemplazo parcial de polvo de ladrillo de arcilla en 25%, demuestran resultados óptimos como mayor resistencia, además de un bajo volumen de contenido de vacíos y una permeabilidad baja. Asimismo, muestra una reducción económica de fabricación por m3 de 8.72%, en comparación a la muestra convencional. / The deterioration of concrete structures due to the attack of external agents, is one of the problems with more emphasis in the construction sector, since it directly affects the properties of the infrastructure, resulting in a reduction in useful life. On the other hand, we have the increase in constructions close to the sea coast, however, the problem of efflorescence, detachment, corrosion or stains on the concrete arises, due to the attack of sulphates present in seawater, in the soil, and in the humidity. Over the years, products such as additions in the cement composition or non-permeable products have been proposed to apply to concrete, in order to minimize the impact. For the present investigation, the effectiveness of brick dust is studied as a partial replacement for cement, through tests of compressive strength, workability in a fresh state, void content volume and permeability. Tests were carried out with four different replacement proportions such as 5%, 15%, 25% and 30%, for a resistance of f'c 300 kg / cm2. According to the results, it was concluded that the samples with partial replacement of clay brick dust in 25% demonstrate optimal results such as greater resistance, in addition to a low volume of voids content and a low permeability. Likewise, it shows an economic reduction in manufacturing of m3 of 8.72%, compared to the conventional sample. / Tesis

Ubytovací zařízení / Accommodation

Šestáková, Tereza January 2022 (has links)
The diploma thesis deals with the project documentation of the accommodation facility - a mountain pension in the village of Rudná pod Pradědem. The building has an irregular floor plan and is divided into two parts. One part of the building is used for accommodation with a capacity of 16 people. It has two floors and consists of a flat, green roof. In the second part of the building, on the first floor there is a cafe, massages and infrared sauna. In the basement there is a technical background of the building. Office space and accommodation unit are located in the attic of the building. It consists of a saddle roof. The building is based on simple concrete foundation strips. The vertical load-bearing structures are made of ceramic blocks and blocks of lost formwork in the basement. Ceiling structures are designed as reinforced concrete, monolithic. The building is designed on a sloping terrain.

Dům s pečovatelskou službou ve Zlíně / Nursing home, Zlín

Kaulincová, Hana January 2022 (has links)
The subject of the thesis is the development of project documentation for the construction of a nursing home in Zlín for clients who are unable to take care of themselves and need full day care. The nursing home is designed to stand alone in sloping terrain. The slope is used and the entrance to the first above-ground level is at the level of the modified terrain from Broučkova street and the entrance to the basement is also from the modified terrain. The building is designed with one underground floor and five upper floors. The circumferential and internal supporting masonry is designed from ceramic cut cinder blocks on the upper floors. Lost shuttering is used on the perimeter and vertical support structures, in the basement. Elevator shafts, ceiling structures and staircases are designed from monolithic reinforced concrete structures. The roof is an extensive green roof. The object is based on reinforced concrete strips. The object is insulated with the ETICS.

Modernizace bytového domu Vlhká 22, Brno / Modernization of apartment house Vlhká 22, Brno

Neduchal, Zbyněk January 2020 (has links)
The diploma thesis processes project documentation in the stage of construction for modernization of an apartment house near the center on the street Vlhká 22 in Brno. The building is divided into four residential floors and nonresidential basement and attic. On the first floor there are two residential units and the other four residential units. The foundation structures are made of solid bricks. The vertical load-bearing and non-load-bearing structures are also made of solid bricks. Exceptionally drywall partitions. In the basement, the ceiling structures are made of brick barrel vaults, above the above-ground floors there are wooden beamed ceilings. The roof structure of the building is made of purlin system with standing stool and covering of ceramic roof tiles. Three additional housing units will be built in the attic. In the basement, the masonry will be undercut by a chain saw, partly by pressure grouting and partly by a new layer with a waterproofing layer. All wood-beamed ceilings will be replaced with prefabricated ceiling beams with aerated concrete inserts without overhead slab. The garden part of the building will be insulated with mineral wool. The roof structure will be constructed from the street side as a shed roof and in the garden part a flat roof with a gradient layer of expanded polystyrene thermal insulation and a waterproofing layer of thermoplastic poleolefin.
