Indiana #53 - Mulzer Crushed Stone, Inc

A Family Business Since 1935 The story of Mulzer Crushed Stone is very much the story of success. It started in 1935 when Roland, Edgar and Arnold Mulzer, Sr. began building culverts for highway construction. In 1946, the Mulzer brothers saw the need for a close supply of construction aggregates during the post World War II construction boom.

Life Cycle Assessment: Past, Present, and Future

Environmental life cycle assessment (LCA) has developed fast over the last three decades. Whereas LCA developed from merely energy analysis to a comprehensive environmental burden analysis in the 1970s, full-fledged life cycle impact assessment and life cycle costing models were introduced in the 1980s and 1990s, and social-LCA and particularly consequential LCA gained ground in the first ...

4 Aggregate Specifications and Requirements

Coarse aggregates are divided into classes based on quality requirements as noted in the Classification of Aggregates table. Class AP is the highest class and is assigned to aggregates which m eet the requirements for all INDOT uses. Some INDOT contracts specify type AP aggregates for use in specific applications of portland cement concrete.

a change in volume with the concrete, right, that can also lead to expansive pressures. So you have 2 different types of manifestations, one is loss of mass from the surface. The other is expansion of the concrete which is caused by several different scenarios, right. So this is a

Permissible Levels of Chlorides and Sulfates in Aggregate

Q. We're designing a concrete structure in Egypt, and I received test results for the aggregate to be used in the concrete. The report lists chloride and sulfate content, but I don't know how to evaluate these numbers because ASTM C 33, "Standard Specification for Concrete Aggregates," doesn't give limits for them.

Helping structural designers to use recycled aggregate concrete

The proposed design, similar to that of conventional structural concrete elements, differs in the application of easy-to-use correction factors accounting for the slight changes on the mechanical and durability-related performance of the new concrete due to the incorporation of recycled aggregates (RAs).

Studies on recycled aggregates-based concrete - Major Rakshvir

Recycled concrete aggregates are different from natural aggregates and concrete made from them has specific properties. The percentages of recycled concrete aggregates were varied and it was observed that properties such as compressive strength showed a decrease of up to 10% as the percentage of recycled concrete aggregates increased.

Green Concrete from Sustainable Recycled Coarse Aggregates

Present investigations deal with the development of green concrete (M 30 grade) using recycled coarse aggregates for sustainable development. Characterization of recycled coarse aggregates showed that physical and mechanical properties are of inferior quality and improvement in properties was observed after washing due to removal of old weak mortar adhered on its surface. The influence of ...

Alkali-Aggregate Reaction - Portland Cement Association

In most concrete, aggregates are more or less chemically inert. However, some aggregates react with the alkali hydroxides in concrete, causing expansion and cracking over a period of many years. This alkali-aggregate reaction has two forms: alkali-silica reaction (ASR) and alkali-carbonate reaction (ACR).
