Abstract:

The pervious concrete system and its corresponding strength are as important as its permeability characteristics. The strength of the system not only relies on the compressive strength of the pervious concrete but also on the strength of the soil beneath it for support. Previous studies indicate that pervious concrete has lower compressive strength capabilities than conventional concrete and will only support light traffic loadings. This thesis investigated prior studies on the compressive strength on pervious concrete as it relates to water-cement ratio, aggregate-cement ratio, aggregate size

Abstract:

Concrete undergoes volumetric changes throughout its service life. These changes are a result of applied loads and shrinkage. Applied loads result in an instantaneous recoverable elastic deformation and a slow, time dependent, inelastic deformation called creep. Creep without moisture loss is referred to as basic creep and with moisture loss is referred to as drying creep. Shrinkage is the combination of autogeneous, drying, and carbonation shrinkage. The combination of creep, shrinkage, and elastic deformation is referred to as total strain. The prestressed concrete beams in the Chickah

One area for sustainable engineering is the efficient use of recycled aggregates obtained from construction and demolition and also as by-products derived from industrial waste that optimises economic and environmental benefits. For the past five decades, studies on the effect of coarse recycled aggregates (RCA) on properties of concrete have been going on, and in fact, none of them reported that good quality coarse RCA, from the mechanical point of view, is unsustainable for structural use. However, according to the limits stated in BS EN 8500 part 2 (2006), at least 87% of the coarse RCA sha

Abstract:

Early and accurate prediction of the compressive strength of concrete is important in the construction industry. Modeling the compressive strength of concrete to obtain a balance and equality between prediction accuracy, time and uncertainty of the prediction is a very difficult task due to the highly nonlinear nature of concrete. For structural engineering purposes, the 28- day compressive strength is the most relevant parameter. In this study, an attempt has been made to predict the 28-day compressive strength of concrete using Relevance Vector Machine (RVM). An RVM belongs to the class of s

Concrete structures may be subjected to dynamic loading during their service life. Understanding the dynamic properties of concrete structures is becoming critical because of the increased concern about the dynamic loading of both civilian and military structures, and especially, the recent increase in terrorist attacks on structures.

The brittleness of concrete has always been a safety and economic issue of great concern. The low tensile strength of concrete is the cause of its intrinsic brittle nature.

After cycling, all samples are loaded to a strain of 0.008.

Many structures within hydropower are made of concrete and the demands on the new supplementing concrete are high.

In recent years great advances have taken place in the use of masonry in building construction. Where as the number of storeys has increased substantially, the thickness of the wall has decreased.

This added a new dimension to the construction and design of masonry structures. Greater flexibility was provided by the use of hollow filled and solid blocks utilising different colours, shapes and texture for interior and exterior masonry elements. The use of hollow blocks pr

碩士<br>國立中興大學<br>土木工程學系<br>93<br>Abstract The object of the research is to investigative the pore structure of fly ash concrete and the relations between porosity and compressive strength. Three water to binder ratios （0.35, 0.50, 0.70） and three substitute ratios of cement with fly ash （10％,20％,30％）were selected for preparing concrete samples. They were tested at 6 ages （0~91 days）for compressive strength and MIP porosity measurement. Test results show that the fly ash concrete consisted of more micropores of under 0.05μm at early age（7 day）, but this portion of micropore

碩士<br>國立臺灣大學<br>造船及海洋工程學研究所<br>89<br>There are two parts in this study. The first is experiment and the second is the model to predict the stress-strain response. FRP wrapped around the concrete columns and the steel-confined concrete columns in order to discuss the difference of their uniaxial-loaded behavior. The result of experiments shows that the FRP confinements of the two kinds of specimens are similar. So, the method to analyse the behavior of FRP-wrapped concrete column can be also used to FRP-wrapped and steel-confined concrete column. This is convenient to experiment. Whe

碩士<br>中興大學<br>土木工程學系所<br>95<br>This research aims to investigate the pore structures of silica fume concrete and finds the correlation of porosity of concrete with the compressive strength. In this research, three water / binder ratios ( 0.35 0.50 0.70 ) and three substitute ratios of cement with silica fume ( 0% 5% 10% ) were selected for preparing concrete specimens. The specimens were tested at six ages (1-91days) for compressive strength and MIP porosity measurement respectively. Test results show that silica fume produce evident filling effect and pozzolanic reaction in concrete at early

Abstract:

The application of nanotechnology in concrete has added a new dimension to the efforts to improve its properties. Nanomaterials, by virtue of their very small particle size can affect the concrete properties by altering the microstructure. This study concerns with the use of nano silica of size 236 nm to improve the compressive strength of concrete. An experimental investigation has been carried out by replacing the cement with nano silica of 0.3%, 0.6% and 1% b.w.c. The tests conducted on it show a considerable increase in early-age compressive strength and a small increase in the overall com

碩士<br>國立高雄應用科技大學<br>土木工程與防災科技研究所<br>95<br>The compressive strength is regarded as one estimated indicator of the concrete quality. Generally, we pick compressive specimens and core specimens to estimate the whole quality of structure. If estimating the true quality of concrete by some nondestructive test method that not only does not damage the structure, but can monitor overall for a long time. The first part of this research is to establish the related equation between nondestructive testing and compressive strength of concrete; the second part, put the testing value of the in-place concrete

According to the ratio of fixed water-cement ratio, natural aggregate and recycled aggregate, this study designed four kinds of ratio, and made two samples for every ratio. Experimental outcomes showed that the compressive strength is inversely p
