business objectives of the organisation. 1.1. Organisation Holcim New Zealand Limited is a leading supplier of cement, aggregates and ready mixed concrete in New Zealand. Its involvement in the New Zealand building industry dates back to 1888. It is part of the regional Holcim Australia/New Zealand business and the global LafargeHolcim Group, the world 's leading supplier of cement, aggregates and construction-related services represented in 90 countries on all continents. The Group has 115,000

and radiopaque (Parirokh et al., 2010; Kratchman et al., 2004) Mineral trioxide aggregate (MTA) is an endodontic material first presented as a root end filling material in 1993 (Torabinejad et al., 1993). It is also used extensively as a reparative cement in root perforations and pulpotomies due to its biological properties (Unal et al., 2010). MTA is composed of silicate oxide, tricalcium silicate, tricalcium

accountable for around 4% of particulate emission. The enormous demand of construction industries has highlighted the requirement for sustainable development and intelligent utilization of resources, pointing towards two commonly used materials i.e. cement and nanomaterial there by substantially used and abused. "Sustainable development meets the needs of the present without compromising the ability of future generations to meet their own needs" -The World Commission on Environment and Development,

The cement was an architectural feature that is used to construct buildings. Cement is made from a mixture of limestone, sandstone, ash, chalk, iron, and clay. Researchers discovered the Roman concrete contained aluminum tobermorite, a rare mineral that adds extra strength. Cement was used by plebeians because they were the farmers, craftsmen, laborers, and soldiers of ancient Rome. If you go to Rome today you can see many ancient ruins that are still there because Romans used a ‘secret’ ingredient

Increasingly, engineers are designing composite and mixed building systems of structural steel and reinforced concrete to produce more efficient structures than realized using either material alone. Recent literature has pointed out a need for greater understanding of the interaction of structural steel and reinforced concrete in such systems. In this paper, the behavior of composite beam-column connections is examined through results of an experimental research program where15 two-thirds scale joint

Sylvester stood leaning forward, with his hands on the rim of the concrete planter. His head hung low. He was sweating freely and he was breathing fast. “Chase,” he said, looking across at him. Chase was on the opposite side of the planter, looking past the scrawny tree at Sylvester. He was also tired. “This isn’t me!” Sylvester told him again. “Wanna tell me what happened back there?” Chase asked. Sylvester gathered up his thoughts and he went on to explain. “Three weeks ago, I had a swell job

five different types of cement in the dental field each is versatile in their properties, uses, and mixing techniques. Many were traditionally used for routine cementation through the nineteen ninety’s and since have been replaced by newer makeup and mixing techniques. The selection of cement for a specific procedure requires knowledge of the chemical and physical properties of each particular cement for the specific restorative process to be performed. This first cement I’m going to discuss is

Entering International Markets Measuring a potential business venture has many aspects which the international manager must be aware of in order to convey the correct information back to the decision makers. Being ignorant to any of the aspects can lead to a false representation of the project, and hence an uninformed decision being passed. In order for a business to survive it must grow. For growth to be optimal, management must first be able to identify the most attractive prospective leads

The Mechanical Behavior of Geopolymers after exposing to High Temperatures Name University Supervisor Due Date: Executive Summary This paper reviews the mechanical behavior of geopolymers after exposing to high temperatures. The review begins with a brief overview of geopolymers and examines the extant literature on the mechanical behavior of geopolymers after exposing to high temperatures by artificial intelligent techniques. The final and compressive strength of geopolymers is
