It depends on what you mean by rock fragments. But, if you are referring to rocks that have bits of blown up pieces of rocks in them, aka pyroclastics, then those are volcanic breccia and tuffs. These are made up of rocks such as rhyolites, andesites, or basalts.
Sedimentary rocks made of weathered rock fragments are called clastic sedimentary rocks. These rocks are formed from the accumulation and cementation of fragments that have been weathered, eroded, and transported from their original source. Examples include sandstone, shale, and conglomerate.
A Clastic sedimentary rock forms when fragments of preexisting rocks are compacted or cemented together. A Bioclastic rock is a clastic rock but the fragments are not of preexisting rock but of organic shell and or bone fragments.
as fragments of rock
A sedimentary rock made up of rounded fragments of other rocks is called a conglomerate.
Breccia is a sedimentary rock composed of angular fragments of other rocks cemented together. It forms when fragments are compacted and cemented together by minerals, creating a mosaic-like appearance. Breccia can consist of a variety of rock types depending on the environment in which it formed.

Clastic sedimentary rocks.
Clastic sedimentary rocks are made of fragments from rocks, minerals, and shells. These fragments, called clasts, are compacted and cemented together over time to form rocks like sandstone, shale, and conglomerate.

Fragmental sedimentary rocks are formed from rock fragments, such as sand, gravel or clay. These fragments become cemented together because of pressure and other chemical reactions.
