The Above Block Fill Mix Design has been tested and approved by contractors in the field. AIRPLACO strongly recommends the use of this mix design with the model PG-25 masonry block fill grout pump. Although no guarantee is given on the use of the mix design it has been proven to work and pump distances required on several jobsites. This Block Fill Mix Design helps ensure the proper consistency of the mix, water content and control over the size of the aggregate rock so that successful pumping can be achieved using the model PG-25 masonry block fill grout pump. AIRPLACO strongly recommends that masonry block fill contractors using the AIRPLACO PG-25 specify this mix design with their material supplier/ready mix company.
