The work is focussed on the physical and chemical characterisation of Thesis of limestone and its effects on pore structure in terms of porosity, water absorption and sorptivitycompressive strength and the durability of the concrete in terms of the carbonation and chloride ingress and the corrosion of steel reinforcement, including a statistical modelling of the carbonation of concrete with Portland limestone cement PLC.
The material was first used for cement, road metal, and sugar refining. In the winter, these blow from the Mohave Desert southward thru the Cajon Pass. Abstract There is an increasing global concern that has led to efforts to lessen the carbon footprint of the cement industry and make concrete manufacturing more sustainable by using other types of materials as supplements or alternatives, primarily for Portland cement PC.
As a consequence of this and of the steep relief, exposures are generally good. In addition it is a station on an interurban line. This should be considered where a higher proportion of GLS content is allowed in the standards.
In the summer the prevailing winds come from the coast thru Santa Ana Canyon. The economic aspects of the deposits were also investigated.
The writer wishes Thesis of limestone acknowledge the help given by Mr.
The highest and lowest point in the area are feet and feet respectively, the relief in general averages less than this. Quarrying operations were started at Crestmore some seventeen years ago.
This range parallels the front of the San Gabriel Mountains and rises above the flood plain of the Santa Ana River in the manner of a typical "inselberg". A light plane table and a Brunton compass were used in determining locations.
The first publication appeared in 1 and since then numerous papers have been published by A. It is also shown that the carbonation rate and chloride ingress into concrete increase with increasing GLS content.
More specifically it includes all, or parts of, sections 31, 32, 33 and 34, T. The purpose of the present investigation was to study the general geology and determine the origin of the minerals associated with the limestone and the other rooks of the area.
Earl MacDonald, for their permission to make a geologic map of the quarries.
Besides the fact that the climate is of the semi-arid type, common for Southern California, this particular district is the center of strong winds. He wishes to thank the officials of the Riverside Cement Company.
Thomas Mullan, chemist for the Riverside Cement Company, has very generously made numerous analyses for the author and has collected samples for him. Rene Engel under whose supervision this work was conducted. The underbrush is not thick and is burned over in a large part.
The quarries offer an excellent opportunity to collect fresh samples. The cement plant and the limestone quarries of the Riverside Cement Company are located at Crestmore.
Near the cement plant the rocks have been covered with dust and have been glazed in such a manner that recognition of rock types is often rendered difficult. Hence the locality is accessible to the geologist and mineralogist both by trolley and by way of good paved highways.
San Bernardino Quadrangle, originally of the scale of 1: This research work is concerned with the analytical systemisation, including the analysis, evaluation and structuring of global published experimental results, of ground limestone GLS used in concrete as a partial replacement of PC.
Crestmore lies on the extreme lobe of the Jurupa Mountains, an east west range roughly eight miles long and three miles wide. With the increased value and demand for cement the quarrying operations were given over entirely to cement materials. Regional drainage flows to the southwest into the Santa Ana River.
The hills to the east of the quarries were mapped on a portion of the U. Mineralogical interest was first aroused when a specimen of blue calcite with monticellite and xantophyllite were sent to A.Introduction 1 Chapter 1. Introduction and outline of thesis Background Limestone is a natural resource defined as a calcareous material or rock with a calcium carbonate.

This research work is concerned with the analytical systemisation, including the analysis, evaluation and structuring of global published experimental results, of ground limestone (GLS) used in concrete as a partial replacement of PC.
Lime products are used in the pulp and paper industry in the recausticizing cycle to recycle sodium hydroxide for use in the pulp digester. Lime products can be used to scrub flue gas in on-site boilers and to treat industrial sludge and industrial waste water generated in the production process at pulp and paper mills.
