Building block material produced by vegetable fiber, industrial ash slag and concrete and production process thereof

The invention relates to a building block material produced by vegetable fiber, industrial ash slag and concrete and a production process thereof. The concrete block material comprises the following components by weight percent: 15-30% of vegetable fiber, 35-45% of industrial ash slag, 20-30% of river sand or 20-30% of aggregate chip powder, 6-8% of cement and water containing 0.5-1.0% of additive, wherein the industrial ash slag comprises the following components by weight percent: 40-60% of gypsum slag, 20-30% of fly ash and the balance of furnace slag or other industrial ash slag; the weight ratio of the gypsum slag to the fly ash is 2:1; and a green body needs to be stood for 30 minutes in the production process. The building block disclosed by the invention is light in weight and good in heat preservation, heat insulation and sound insulation; and with the adoption of the building block, not only the recycling of the resources can be realized, but also the damage on the ecological system and pollution on
