Hemp Crete hurd, GROWN IN USA, pesticide free.  to make HempCrete use 1 part hemp hurd, 2 parts water and 1.5 parts binder such as lime. 

Our Premium Midwest grown hemp hurd is the perfect 1/2 piece size for HempCrete. 10 Lbs = 51 Liters and 28 Lbs = 142 Liters ours is  the perfect solution for Deep Eco conscious builders and crafters looking for a high-quality, sustainable, and eco-friendly, natural building material to make Hemp Crete. Larger size hemp hurd can also be used for plant or garden mulch as well as Animal bedding for those who want a larger grade of hurd.  Hemp hurd has a high silica content which traps and suppresses ammonia odor as well as moisture as a mulch and obviously absorbs and creates a structure with the lime and water for amazing hemp crete that is anti fungal and mold resistant, soundproof, fireproof, ecologically friendly.

Crafted from 100% natural Midwest grown hemp hurd, the interior woody part of the hemp stalk.

Features:
  • Made from 100% natural Midwest grown industrial hemp 
  • Dust-free, fiber free premium average 1/2 inch size for the finest hemp crete
  • Easy, strong insulative wall building, self repairs, takes plaster readily
  • Soundproof R30 insulation naturally
  • Naturally anti-bacterial and anti-fungal
  • Super insulative for ecological living
  • Very Fire Resistant for a super safe home
  • Breathable, healthy, comfortable interior with sturdy hempcrete walls
  • Carbon Negative
Benefits:
  • Hi insulation capability, non-toxic, sturdy and long lasting building material
  • Carbon negative material
  • Reduces reduces mold growth, anti-fungal
  • Alternative to energy intensive concrete, carbon negative, no energy required
  • Increases structure's strength while providing insulation similar to fiberglass without dangerous chemical outgassing
  • Reduces waste and promotes sustainable farming practices by using a renewable resource, improves all soil properties, captures carbon 
  • Quiet soundproof walls easily takes plaster

•Hemp blocks were tested for fire behaviour and resistance.
•Fire resistance, heat release rates, calorific value, and smouldering were studied.
•Discolouration and charring were observed and quantified.
•Hemp blocks have a low propensity to contribute to fire severity and spread.
•2-h fire resistance rating achieved.
Hemp blocks, also known as hempcrete, are eco-friendly and sustainable construction materials composed of hemp, lime, and water. In this study, the fire behaviour and structural performance of hemp-based materials were experimentally investigated. Fire exposure scenarios using raw hemp shives, hemp blocks, and non-load-bearing hemp block walls were examined. Tests conducted include cone calorimeter, bomb calorimeter, standard furnace, heat-transfer rating inducing system (H-TRIS), and small-scale elevated temperature material tests. Hemp shives exhibit ignition with sustained flaming, a relatively high heat release rate (HRR), and a relatively low critical heat flux (CHF). However, the hemp blocks exhibited no flaming ignition, only smouldering combustion, and an HRR an order of magnitude lower. Hemp blocks and hemp shives produced minimal smoke. Hemp blocks charred, and associated discoloration zones have been documented. Tests indicate that limited structural capacity is lost up until 200 °C, whereas at 300 °C, the residual material strength is almost negligible. The hemp block walls maintained their structural stability and integrity for 2 h of standard fire testing. The ambient-temperature compressive strength of the hemp blocks was determined to be 1.0 MPa. This work is the first comprehensive study on the fire behaviour of hemp blocks and highlights their good performance, whereby they are likely to have a limited impact on fire risk in buildings. Plastered walls will have a fire performance exceeding those reported here.
