The quarter minus rock size can consist of rock in diameter as big as 1/4" in size and "fines" (anything smaller than the maximum allowable rock size (which in this case is 1/4), even as small as stone dust). Any aggregate with the name "minus" can contain up to 80% fines. Quarter minus is mostly used as filler aggregate for bigger aggregate, empty space between two different sized aggregate, vehicle parking grade, and landscape surfaces. A positive of using quarter minus as a landscape aggregate is that it does not provide a home for pests and does not decompose like other landscape aggregates like wood-chips, for example. == References == - [[Interior Architecture/Renovation and Conservation]] - [[Digital Architecture/Computational Design/Learn BIM]] - [[Building Services/Vertical Transportation]] - [[Urban and Planning/Smart Buildings]] - [[Building Construction/Hill Architecture]] - [[Professional Practice/Codes & Standards/National Building Code of India/Part 08 - Building Services/Section 5B - Escalators and Moving Walks]] - [[History and Theory/Temple Architecture/Stone Temples of India/satellites]] - [[Environmental Design/Daylighting Design]] - [[Professional Practice/Codes & Standards/National Building Code of India/Part 08 - Building Services]] - [[Professional Practice/Codes & Standards/National Building Code of India/Part 11 - Sustainability]]
