New Products to be Unveiled at Booth S6835 – Details to be Released at Show
Booth to Feature Live, Three-dimensional Performance by World-renowned Sand Sculptors

CAMBRIDGE, Massachusetts, February 9, 1999 — Grace Construction Products, a world leader in the construction products industry, will showcase its latest product and service innovations at ConExpo-Con/Agg '99, booth S6835, in Las Vegas, March 23-27, 1999. Featured products, demonstrations, and services will include an enhanced version of the company's highly acclaimed DuraModel™ Software, ADVA® Superplasticizer, and PolarSet® non-chloride accelerator.

ConExpo-Con/Agg also will serve as Grace's stage for the introduction of exciting new products. The company will release new product details at the show on opening day.

Reinforcing its Las Vegas presence, Grace will feature, at its booth, a live, three-dimensional performance by a team of world-renowned sand sculptors. This "work in progress" will ultimately and uniquely simulate the Las Vegas skyline. Members of Sand Sculptors International, who have carved their creations at special events and competitions throughout the United States, Europe and Asia, will work throughout the course of the show to complete the sculpture. The sculpture will be built on a platform measuring 10'x12' and will reach 10' in height.

"Las Vegas is the home to a number of highly visible buildings constructed with Grace products, including ADVA Superplasticizer and PolarSet", said Alice Poltorick, Marketing Communications Manager. "Clearly this city serves as a meaningful backdrop to showcase existing products and launch new products. Our strong industry presence will extend well beyond the trade show floor."

The Grace Construction Products booth will feature a Technical Services area staffed by a petrographer and technical service specialists. Equipped with a Petrographic microscope and a Stereomicroscope, staff will be on hand to demonstrate concrete analysis - reviewing the concrete microstructure, cement hydration and admixture effectiveness, air content, microcracking and mixing effectiveness - using concrete samples. Grace's Technical Services Laboratory Group often dissects samples of concrete to address specific project related issues. It is an innovative, ongoing service offered by Grace Construction Products to its customers worldwide.

"Our construction products and services are born from an intensive R&D effort, technical expertise and market knowledge," said Poltorick. "Grace Construction Products is dedicated to raising industry standards and providing superior products and technical support to all of our customers. With the introduction of each new product and service, we reinforce our commitment to excellence."

DuraModel™ Software

Grace Construction Products' DuraModel Software, introduced in June 1997, enables Grace representatives to provide on-site, in-depth analysis of clients' corrosion protection alternatives, in a matter of minutes. An updated version of this software boasts new features and enhancements based on customer response, and DuraModel demonstrations will be available at Grace's booth throughout the length of the show.

Designed to simulate the complexity of life cycle costs and analyze corrosion protection alternatives quickly, the DuraModel software now features the ability to address multiple sealer and membrane applications and to determine the apparent diffusion coefficients from concrete field cores. Service life results can now be predicted based on local and regional concrete exposure and permeability. This enhanced DuraModel analysis is much more specific to local conditions. After the show, an interactive preview of the DuraModel program can be accessed from the Grace Construction Products' web site at

The DuraModel Software offers a uniform, scientifically based evaluation method to compare all available corrosion protection products and systems. This software gives clients the information they need to make better, more cost-effective decisions about corrosion protection. Easy-to-understand results are graphically displayed and a 23-page color report is available to clients. This analysis is a free service of Grace Construction Products and is ideal for clients such as architects and engineers who specify concrete in corrosive environments. This program has received widespread acceptance and acclaim from a variety of users including State Departments of Transportation, City Municipalities, Port Authorities, major engineering design firms and general contractors around the world.

ADVA® Superplasticizer

ADVA Superplasticizer is a breakthrough advancement in superplasticizer technology. This high range water-reducing admixture combines, for the first time, the benefits of long slump life with near neutral set time in high strength concrete. The result of years of research and development, this product is used at approximately 1/3 the dose of a normal superplasticizer. This low dose produces high slump concrete with little segregation, and the concrete has superior workability and finishing characteristics. At ConExpo, testimonials about projects from around the world that have benefited from using ADVA Superplasticizer can be heard in an exciting video, entitled "The Time Is Right™".


PolarSet is a non-corrosive, non-chloride, set accelerating admixture for concrete. It accelerates cement hydration resulting in shortened setting times and increased early age strengths, especially in cooler temperatures. PolarSet can reduce concrete set times by hours, thus enabling the earlier removal of protective tenting, faster form stripping, and quicker finishing. PolarSet, designed without the potential corrosive effects found with calcium chloride products, is especially useful where potential corrosion of embedded or stressed steel must be avoided. It can also be used in concrete that is to be placed on steel clad or zinc coated steel decks.

For more information on DuraModel, ADVA, or PolarSet, customers can contact their local Grace Construction Products salesperson or visit ConExpo-Con/Agg booth S6835. Also, Grace's web site address is ../index.html.
