For
nearly a century Haydite has been used successfully around the world in many different
types of applications. The most notable among these are concrete masonry, high-rise
buildings, concrete bridge decks, precast and prestressed concrete elements, soil
conditioner and geotechnical fills.
What is Haydite? It is a unique, ceramic lightweight
aggregate prepared by expanding select shales in a rotary kiln at temperatures over
1000'C. The production and raw material selection processes are strictly controlled to
insure a uniform, high quality product that is structurally strong, stable, durable and
inert, yet also lightweight and insulative. Haydite gives designers greater
flexibility in creating solutions to meet the challenges of dead load, terrain, seismic
conditions, construction schedules and budgets in today's marketplace.
Structural Concrete
Haydite
structural lightweight concrete solves weight and durability problems in buildings and
exposed structures. Haydite concrete has strengths comparable to normalweight concrete,
yet is typically 25% to 35% lighter. Haydite offers design flexibility and substantial
cost savings by providing less dead load, improved seismic structural response, longer
spans, better fire ratings, thinner sections, decreased story height, smaller size
structural members, less reinforcing steel, and lower foundation costs. Precast elements
have reduced transportation and placement costs. The excellent durability performance of
Haydite is a result of the ceramic nature of the aggregate, and its exceptional bond to
and elastic compatibility with the cementitious matrix.
Pumping Haydite Concrete
Today most lightweight concrete is placed through the use of concrete pumps. The porous nature of Haydite aggregate may cause the material toabsorb water when subjected to pumping pressures. Therefore, to achieve maximum
pumpability for Haydite lightweight concrete, presoaking the lightweight aggregate is
required. The presoaking process aids in preventing the aggregate from absorbing water
during the pumping process and allows the concrete to be delivered in a ready-to-pump
condition. This minimizes slump loss, increases pumpability and maintains consistency.
Special stockpiles of material are maintained
in a prewet or saturated condition for pumping of lightweight concrete.
Mix Design
Contact Hydraulic Press Brick Company for mix
designs and technical support when preparing for a lightweight concrete project. Haydite
representatives work with lightweight concrete mix designs and pumping on a daily basis.
They can provide you with valuable information and resources that can save you time and
money.
Specialty Concrete & Miscellaneous Uses
The
superior qualities of ESCS are effective and economical in many other applications.
Examples include wood floor topping, bagged concrete mix, cement wallboard, artificial
stone, refractory, roof tile, traction grit, grog, insulating fill and many, many more.
Expanded shale, clay and slate
aggregate, as manufactured by the rotary kiln process (originally developed in 1908
and patented in1918 as Haydite), is available throughout the world.
