Here we have switched hammers to the larger D62 hammer for phase two of our installation testing. In phase two, we were attempting to break the piling by applying as much vertical force as possible to the top of the pile.
Construction crews know how to get a batch of concrete mixed, poured, and leveled. At job sites around the country (and the world), construction professionals use standard machines and well-known techniques to do the job right.
Concrete is the foundation of modern construction. Its strength and durability enables it to support heavy structures over long periods of time. Compressive strength is the prominent concrete specification, but tensile, flexural, and other properties can play a significant role in modern designs.
is the world’s preeminent authority on concrete research and industry standards. Based in Michigan and founded in 1904, ACI develops technical standards and certification criteria for the production, installation, and maintenance of concrete. Building and design codes at the local, state, federal, and international levels increasingly rely on ACI publications to establish specifications for concrete construction.
The use of ultra-high-performance concrete is becoming more common, thanks in no small part to the fact that it can now be mixed, transported, and poured using standard ready-mix trucks. The cost is also coming down, because you don’t need to buy a concrete manufacturer’s sand or cement; you can use your own. More on that in a bit.
The cost of construction materials can be just as important as the quality. Ultra High-Performance Concrete (UHPC) checks all the boxes for quality, but many still worry that the price is too high. The question on everyone’s mind seems to be: “When will the cost of UHPC come down?”
More than 30 years of research and recent commercial success have proven the promise of Ultra-High Performance Concrete (UHPC). Its strength and durability have brought UHPC into the spotlight for public agencies and private firms seeking superior alternatives for concrete construction.
