What is sand? Composition & Types of Sand - Civil Engineering

Sand is basically made of unconsolidated granular materials consisting of either rock fragments or mineral particles or oceanic materials. It is mainly made of silicate minerals and silicate rock granular particles. Typically quartz is the most dominant mineral here as it possesses highly resistant properties to weather.
