Block sizes can be varied to suit your job specifications.Sandstone is a sedimentary rock composed of sand-size grains of mineral, rock, or organic material. It also contains a cementing material that binds the sand grains together and may contain a matrix of silt- or clay-size particles that occupy the spaces between the sand grains.By moving from clean sandstone (grain-supported) toward arenite and so on, clay content increases and rock turns into shaly sandstone. Therefore, grain-to-grain contacts decrease and rock microstructure changes into matrix-supported sand-shale mixture. As clay content increases further, the given rock alters to sandy-shale and mudstone.Phone: 435-772-3256. If you have questions, please email [email protected].
