TH22236U - Hemp concrete with aluminum sulfate used for quality improvement. - Google Patents

Abstract

------06/07/2021------(OCR) Hemp concrete using aluminum sulfate for quality improvement consists of Portland cement type 1, sand, dry hemp core, water, a large amount of water-reducing agent, aluminum sulfate, and optional calcium hydroxide. Hemp core, crushed to a small size and improved with aluminum sulfate and calcium hydroxide, is mixed with cement, sand, and water. This mixture is then poured into formwork and left to harden in the hemp concrete, which is then air-cured. The objective is to utilize hemp concrete as a construction material for wall construction, providing thermal insulation and energy savings. Furthermore, it aims to facilitate its application in various non-load-bearing and medium-load-bearing concrete components, and to support future hemp cultivation. ------------ Page 1 of 1 page. Abstract of the Invention: This invention describes a process for producing hemp core-mixed concrete, or "hemp concrete." Hemp core, crushed to a small size and improved with aluminum sulfate and calcium hydroxide, is mixed with cement, sand, and water and then poured into formwork. Released into hemp concrete and hardened by air curing, the aim is to utilize hemp concrete as a construction material, specifically as a wall material for thermal insulation and energy saving. Furthermore, it aims to be applicable to various concrete construction components, both load-bearing and medium-load-bearing, and to support future hemp cultivation.

Hemp concrete using aluminum sulfate for quality improvement according to claim 1 or 2, where the hemp core mixture has a particle size of 2-10 mm. ------------ Revised 07/11/2018 Claim 1. Hemp concrete using aluminum sulfate for quality improvement According to this invention, the production of hemp concrete using aluminum sulfate and calcium hydroxide for quality improvement, as per Patent 1, consists of: - 1 part by weight of Portland cement type 1; - 1-4 parts by weight of cement of sand; - 10-25% by weight of cement of dry hemp core; - 35-55% by weight of cement of water; - 0.1-2% by weight of cement of bulk reducing agent; - 5-30% by weight of hemp core of aluminum sulfate (alum); - 0-60% by weight of hemp core of calcium hydroxide (lime). 2. Production of hemp concrete using aluminum sulfate and calcium hydroxide for quality improvement, as per Patent 1, where the hemp core mixture has a particle size of 2-10 mm. ------------ Page 1 of 1 page. Patent 1. Production of hemp concrete using aluminum sulfate and calcium hydroxide for quality improvement, as per this invention, consists of: - 1 part by weight of Portland cement type 1. - Sand: 1-4 parts by weight of cement - Dry hemp core: 10-25% by weight of cement - Water: 35-55% by weight of cement - Bulk reducing agent: 0.1-2% by weight of cement - Aluminum sulfate (alum): 5-30% by weight of hemp core - Calcium hydroxide (lime): 0-60% by weight of hemp core 1. The production of hemp concrete using aluminum sulfate and calcium hydroxide for quality improvement, as described in this invention, consists of: 2. Production of hemp concrete using aluminum sulfate and calcium hydroxide for quality improvement, according to Patent 1, where the hemp core mixture has a particle size of 2-10 mm. 3. The process for producing hemp concrete using aluminum sulfate and calcium hydroxide for quality improvement involves the following steps: a. The deboned hemp core is air-dried or oven-dried to remove moisture. b. The core from step 1 is crushed to reduce its size to an average of 2-10 millimeters. c. The hemp core from step 2 is then improved with aluminum sulfate (alum) and calcium hydroxide (lime) in the specified ratios for 15 minutes. d. The resulting hemp core is mixed with Portland cement type 1, sand, water, and a significant amount of water-reducing agent in the specified ratios. The mixture is then mixed thoroughly for 3 minutes. The workability is checked; it should be able to be poured into molds as desired. e. 5% to 90% fly ash can be used as a substitute for Portland cement type 1 in the specified ratios.
