New consolidation tools address current concrete design and construction practices.
SI 400 preblended portland lime mortars offer smooth consistency, easy workability, and superior bond strength.

Under what conditions are we allowed to retemper ready-mixed concrete at the jobsite? If we receive a batch that has too low a slump, can we add water to make the concrete more workable?
When self-consolidating concrete (SCC), first billed as self-compacting concrete, was developed several years ago some thought it would quickly take a significant share of the concrete market and there were many claims made about its properties and what it could do.

Construction equipment manufacturers expect overall industry business to turn around slightly in 2010 following double-digit expected year-end 2009 declines in the minus-40-percent range for the United States and minus-30-percent range for Canada and other worldwide sectors, according to the annual...
Modern concrete technology has uncoupled workability with water content through the use of surface active dispersants that interfere with the natural flocculation process of unhydrated cement in water.

We have our first large self-consolidating concrete (SCC) project coming up soon, so I want to ensure that we get this right. The engineer performed the required test mixes to confirm slump, flow, spread, and compressive strength performance. The mix from
Sixteen bridges with more than 300 columns, 250 bridge caps, and 900,000 square feet of bridge deck have only two years for construction, from start to completion.

Garmin International is a worldwide leader in the design, manufacturing, and marketing of navigation and communication products utilizing GPS technology. From a handful of employees in 1989, the organization has grown to more than 7000 associates worldwide. Growth of this magnitude has resulted in...
The Slump Master III Safety Inspection Platform provides safe and convenient access for checking concrete slump.
Concrete that flows into rebar-congested forms under its own weight, with no vibration and no segregation, is the dream of every contractor.

In April 2008, Grace Construction Products and RS Solutions entered into an agreement, where Grace became the exclusive sales and marketing agent for the Ready Slump system to ready-mix concrete producers worldwide.
Placing and finishing lightweight concrete can be a tricky and risky task. Success requires teamwork from the owner, architect/engineer, general contractor, ready-mix producer, and concrete contractor.
According to Ken Simonson, chief economist for The Associated General Contractors of America (AGC), “Nonresidential construction spending continued growing in July, despite the weak economy and housing slump.”

"But Congress...
The Flex-shaft concrete vibrator series offers eight models designed to work in medium- to high-slump concrete.
Chances are that when a load of concrete shows up at the jobsite, somebody's going to add some water. And that's not necessarily a bad thing.
Every ASTM standard test is supposed to include statements on its precision and bias, which are a lot like the fine print on a legal document. These two sections describe how accurately one can expect the test results to reflect the true condition of what's being tested, and in that way, also are a...
It's always interesting to know what the changes are in the admixture industry because they have so much impact on the properties of concrete as well as how it places and finishes. Admixtures also have a profound impact on how contractors do their work and how their bottom line is affected.
Macro polymeric fibers (MPF) have been used in numerous slabs on ground providing amazing performance for various applications.
