Abstract
Mechanically strong, water-disintegrable agglomerates for use as a soil conditioner produced from cement kiln dust and other particulate calcium sources containing CaO or Ca(OH).sub.2 and other calcium-containing compounds having the potential to be hydrated and a process for forming such agglomerates are disclosed. The process comprises combining the particulate calcium source and a water-soluble binder to produce agglomerates which are then subjected to controlled drying such that the dried agglomerates having a size ranging from -7 to +8 Tyler Standard Sieve Series exhibit an average green crush strength of at least about 2 pounds (about 0.9 kg).
