Bottom mud non-sintered ceramsite and preparation method thereof
The invention relates to bottom mud non-sintered ceramsite and a preparation method thereof. The unfired ceramsite comprises the following components in parts by weight: 60 parts of bottom mud, 40-50 parts of Portland cement, 5-20 parts of semi-hydrated gypsum, 5-20 parts of slag, 20-30 parts of distilled water and 50 parts of water-borne epoxy resin. The unfired ceramsite is prepared by the following steps: preparing bottom mud powder, preparing mixed slurry, granulating, curing, modifying and soaking, the preparation process is simple and free of sintering, the variety of the product is easy to adjust, functionalization is convenient to achieve, the prepared unfired ceramsite is low in water absorption and good in mechanical property, the problems that bottom mud ceramsite is small in solid waste mixing amount and poor in mechanical property, and the volume stability is poor due to water absorption are solved, and technical support is provided for river sludge recycling.
本发明涉及一种底泥免烧陶粒及其制备方法。该免烧陶粒包括底泥、硅酸盐水泥、半水石膏、矿渣、蒸馏水、水性环氧树脂，各组分的重量份数分别为60份、40～50份、5～20份、5～20份、20～30份、50份；该免烧陶粒通过底泥粉料制备、混合浆料制备、造粒、养护、改性、浸泡后制得；本发明的制备工艺简单、免烧结，产品的品种易调节，方便实现功能化，制备的免烧陶粒吸水率低、力学性能好，解决底泥陶粒固废掺量少、力学性能差、因吸水导致体积稳定性差的问题，为河道污泥回用提供了技术支持。
