Besides the production of high-performance concrete, superplasticizers are also commonly used in the production of high-workability concrete. with a slump value of 180230 mm, high-workability concrete can be pumped rapidly over long distances, easily compacted in structures with highly congested reinforcement, and can even be self-compacting i.e., requiring no external compaction effort.
For instance, portland cements and blended hydraulic cements for concrete in the u.s. conform to the american society for testing and materials astm c150 standard specification for portland cement, c595 standard specification for blended hydraulic cement or c1157 performance specification for hydraulic cements.
Aug 01, 2016nbsp0183321. introduction. in coal power plants, classification of coal particles in a classifier after the pulverization process is important. a high-quality classification can guarantee the delivery of standard pf efficiently, which results in not only primarily reducing the loss of unburned carbon, but also decreasing the slagging potential in the furnace .
These hvac air filters are usually applied to residential homes, workplaces and buildings. hvac air filters with merv 5 to 8 capture at least microbiological growth hair sprays and fabric protectors cement and pudding mixes hvac air filters with a merv rating between nine and 12 capture particulate matter between 1.0 and 3.0 microns.
Astms cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.
Citeseerx - document details isaac councill, lee giles, pradeep teregowda we extend hoeffding bounds to develop superior probabilistic performance guarantees for accurate classifiers. the original hoeffding bounds on classifier accuracy depend on the accuracy itself as a parameter. since the accuracy is not known a priori, the parameter value that gives the weakest bounds is used.
