“…an agricultural waste) as a sustainable aggregate solution of lightweight concrete and as an alternative to commonly applied products such as: expanded clay, particles of expanded polystyrene (EPS), particles of cork or other lignocelluloses wastes [10]. Since corn cob is generally considered an agricultural waste, an interesting economic and sustainable benefit may be achieved through this proposed technological solution.…”

Taking into account that corn cob, after extracting the corn, is generally considered an agricultural waste, an interesting economic and sustainable benefit may result by using it as a building material. Therefore, it can be an alternative sustainable lightweight aggregate solution in comparison to the most currently applied ones such as expanded clay, particles of cork, particles of expanded polystyrene (EPS), among others. The density, the compressive strength and the thermal insulation properties of a corn cob concrete were experimentally quantified. An expanded clay concrete was also studied as reference. The main results obtained are presented and discussed showing that the proposed corn cob concrete may have the adequate material properties required for a lightweight concrete for non-structural application purposes.

“…This may be due to the organic property and smoothness of CS in the concave side. Similar failure pattern in palm shell concrete due to weak interface bonding was observed [10]. As the target was to achieve a low cost concrete, low cost pre-treatment techniques like cold water extraction, hot water extraction and lime water extraction was carried out and its characteristics was studied.…”

“…Coconut coir possesses high lignin and low cellulose similar to coconut shell which makes them strong and durable. Also mechanical and durability properties of wood cement composites was improved by adding pozzolanic materials like fly ash, silica fume, GGBFS and metakaolin [10]. In addition pre-treatment was carried out by researchers on palm shell which is effectively used as light weight aggregate.…”

Abstract. Low cost sustainable structural green concrete produced using lignocellulosic waste (coconut shell) and industrial waste (ground granulated blast furnace slag) was investigated in this study. Various cost effective pre-treatments were carried out on coconut shell such as cold water extraction, hot water extraction and lime water extraction to remove the extractives (hemicelluloses, phenols). This primarily enhances the interface bond strength leading to increased strength of concrete. Workability and compressive strength of the concrete incorporating untreated and pre-treated coconut shell was investigated systematically. Hot water extraction of coconut shell proved to be an effective method to improve the compressive strength of concrete when compared to other pretreated coconut shell concrete mixes tested in this study. Among the various concrete mixes investigated a maximum compressive strength of 27.0 MPa was achieved using hot water extracted coconut shell incorporated concrete composites.

-The paper presents application of cellulose fibres in a pulp form from waste paper to mortar or plaster. The pulp from waste paper substitutes a part of inorganic filler or binder in cementitious composites. The characterization of properties and use of mortar or plaster mixtures as well as wood pulp fibres used in cement-based materials is presented in the article. The results of testing the technically important parameters (density, water resistance, coefficient of thermal conductivity, tensile strength at bending) of composites which were obtained by compiling the available works are summarized.
