Evaluation of the incorporation of construction waste (CW) for the stabilization of soil-cement mixtures
(ANTAC - Associação Nacional de Tecnologia do Ambiente Construído, 2020)
Use of the HDS system (hydric depuration with soils) associated to other constructed wetlands techniques for public water supply
(1999-10-19)
Two projects of water treatment for public water supply were developed and operated by using combined systems of constructed wetlands. One of the projects was carried out in the town of Analandia, Sao Paulo, Brazil and ...
Avaliação de blocos de solo-cimento utilizando o solo de pato branco corrigido com areia natural ou areia de britagem
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2017-06-22)
Currently, the construction industry is one of the largest consumers of raw materials coming from nature and one of the main generators of solid waste, so it is important to study new building materials that are less ...
Settlement of Footings on Compacted and Natural Collapsible Soils upon Loading and Soaking
(2021-04-01)
Collapsible unsaturated soils experience large volumetric compressive deformations upon wetting. Soil collapse is a geotechnical problem that occurs in different regions of the world and profoundly impacts buildings and ...
Improvement of collapsible soil behavior of a lateritic soil using rice husk ash
(2016-01-01)
Great areas of Brazil present lateritic soils, such as the northeast and the south. Some of these soils have, as main characteristic, instable structures that can present considerable volumetric deformation in the presence ...
Soil compressibility and least limiting water range of a constructed soil under cover crops after coal mining in Southern Brazil
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The use of cover crops affects the support capacity of soil and least limiting water range to crop growth. The objective of this study was to quantify preconsolidation pressure (sigma(p)), compression index (CI) and least ...
Avaliação do potencial de colapso de um solo laterítico compactado através de ensaios oedométricos
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2023-03-17)
In the northwest region of the state of Rio Grande do Sul, it is common to find lateritic soils with medium to clayey texture, which have high porosity and are not saturated. The variation of humidity in this type of soil ...
Recuperação das propriedades físicas do solo por meio de adubos verdes, calagem, gesso, pastagem e espécies de ocorrência espontânea
(2011-07-01)
Inadequate usage can degrade natural resources, particularly soils. More attention has been paid to practices aiming at the recovery of degraded soils in the last years, e.g, the use of organic fertilizers, liming and ...
Determinação dos parâmetros de compressibilidade em amostras de solo mole reforçadas com a incorporação de colunas de areia
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Construção Civil, 2012-06-19)
With the huge growth of urban centers and consequently the impossibility of choice of grounds with soils considered good. Methods of improving soil are a constant challenge and daily renewed for the foundation and geotechnical ...
Fluidization in insect constructions in soils
(Taylor, 2000-06)
Fluidization, a special case of liquefaction, is a physical process occurring in unconsolidated, water-saturated, sediments that can be verified in insect constructions in soils. Behavioral analysis of the bees Ptilothrix ...
