Sand: The Fine Aggregate | SpringerLink
Natural aggregates are the most valuable non-fuel mineral commodity (Lüttig 1994).It is estimated that about 15 billion tons of aggregate materials worth 76 billion dollars are being produced annually throughout the world (Regueiro et al. 2002).Readily available supply of quality aggregate resources are essential to maintain the infrastructure development of the …
Cache-Based Aggregate Query Shipping: An Efficient …
Our study introduces a novel distributed query plan refinement phase in an enhanced architecture of distributed query processing engine (DQPE). Query plan refinement generates potentially efficient distributed query plan by reusable aggregate query shipping (RAQS) approach. The approach improves response time at the cost of pre-processing time. …

The present study aims to study the treatment of (RCA) faction (16/25) by their encapsulation into cement slurry with a (W/C) ratio of (0.5). A complete factorial plan 2 3 was applied by considering three independent factors, namely the state of RCA (GR), the soaking time into slurry (DT) and the hardening time (RCA) (A). The selected responses are the compressive strength and the …

Relational aggregate query processing techniques for real …
We use data samples and statistical methods to construct an approximate response to a given aggregate query when there is not enough time to completely process the query. This thesis considers only COUNT(E) type queries, where E is an arbitrary relational algebra expression.
How to Do Exposed Aggregate Concrete
One top-surface retarder product is Surface Deactivator by Brickform, which provides ten exposure depths, from a simulated light acid etch or sand blast finish up to full exposure of 1 ½" aggregate. Surface Deactivator offers an extended window before the surface paste is removed, allowing the concrete to harden properly, which locks in the aggregate and decreases pop-outs.

Range aggregate processing in spatial databases
A range aggregate query returns summarized information about the points falling in a hyper-rectangle (e.g., the total number of these points instead of their concrete ids). This paper studies spatial indexes that solve such queries efficiently and proposes the aggregate Point-tree (aP-tree), which achieves logarithmic cost to the data set cardinality (independently of the …

Aggregates for Concrete
aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone. Crushing, screening, and washing may be used to process aggregates from either sand and gravel deposits or stone quarries. Aggregates may be produced from igneous, sedimentary, or metamorphic rocks, but geological type does not by itself make an aggregate
