Ultra-high performance fiber reinforced concrete (UHPFRC) has arisen from the implementation of a variety of concrete engineering and materials science concepts developed over the last century.
2020/6/29· After all the pre-pour considerations with regard to an HPLMC pour - such as surface preparation and saturation, the calibration of the mobile mixer and set up of the finish machine - …
2019/6/17· This type of concrete must meet special project requirements in terms of placement and flow. Self-compacting concrete with a similar water cement or cement binder ratio will usually have a slightly higher strength compared with traditional vibrated concrete , due to the lack of vibration giving an improved interface between the aggregate and hardened paste.
High volume production and placement (via hose) of foam concrete is a continuous operation from a mobile central plant on loion. Since the foam is the largest volume contributor in foam concrete , limited deliveries of the raw materials are required, which results in minimal disruption to …
