Materials characteristics affecting CO2 curing of concrete blocks
2016年3月1日 As shown in Table 3, five series of concrete block mixes were designed corresponding to the variables that were designed to be studiedThe concrete blocks were designed using a dry mix (zeroslump) method as the casting and compaction would be done by a high pressure compaction equipment [30], [31], [32]In order to obtain the 2013年1月1日 2 Experimental programme Experimental research of hollow concrete block masonry was carried out at the Department of Reinforced Concrete and Masonry Structures of Vilnius Gediminas Technical University 4 series of masonry specimens were tested Samples were made using S6 (SM6) and P620 (30) hollow concrete blocks (Fig 1)Experimental Research of Hollow Concrete Block Masonry Stress 2015年11月1日 This paper aims to investigate the influence of three different comminution and sizing processes (simple screening, crushing and grinding) on the composition, shape and porosity characteristics of RCA obtained from concrete block waste Crushing and grinding implies a reduction of RCA porosity However, due to the presence of coarse Comminution and sizing processes of concrete block waste
Concrete aggregates properties crushed by jaw and impact secondary crushing
2019年1月1日 The coarse aggregates obtained by different crushing mechanisms (jaw and impact crushers) show very similar characteristics in terms of binder content assessed by acid leaching (275 and 266 wt%), water absorption (876 and 975 wt%) and porosity (186 and 202 vol%)Thus, it is not possible to conclude that any of these mechanisms 2021年1月24日 Concrete hollow block masonry is widely used in North American and Australasian countries because it enables to accommodate grouting and reinforcement to resist higher axial and lateral actions (PDF) Compressive Strength and Deformation Characteristics of Concrete 2023年9月1日 The importance of curing cannot be overemphasized for concrete to be able to actualize desired durability and strength (O D Atoyebi et al, Citation 2019; Ramamurthy Narayanan, Citation 2000; Xue et al, Citation 2015) The idea behind curing is to maintain the concrete as nearly wet or saturated during cement hydration (AlGahtani, Citation Effect of curing methods on the strength of interlocking paving blocks
Stress–strain model for hollow concrete block masonry
