Autor: Samuel Pantaleo, Florent Gauvin, Katrin Schollbach, H.J.H. Brouwers
Publikováno v: Developments in the Built Environment, Vol 20, Iss , Pp 100576- (2024)
Silica aerogel stands out as an exceptional thermal insulation material and is a great candidate for modern and energy-efficient buildings. However, silica aerogel also faces many challenges, mainly due to its expensive, unsustainable and difficult s

Autor: Muhammad Jawad Ahmed, Katrin Schollbach, Sieger van der Laan, Miruna Florea, H.J.H Brouwers
Publikováno v: Materials & Design, Vol 213, Iss , Pp 110329- (2022)
In this paper, the synthesis of dicalcium silicate (C2S) via sol-gel (acid-catalyzed) process including aqueous route, non-aqueous route, and the Pechini method is reported. The composition of C2S (α, β, and γ) polymorphs, by-products, and amorpho

Re-cementation effects by carbonation and the pozzolanic reaction on LWAs produced by hydrated cement paste powder
Autor: Yanjie Tang, Gang Liu, Katrin Schollbach, Yuxuan Chen, Wei Chen, H.J.H. Brouwers
Publikováno v: Journal of Cleaner Production, 377:134529. Elsevier
This paper aims to evaluate lightweight aggregates produced with hydrated cement paste powder (HCP) using both carbonation and normal curing. The comparative study was conducted to figure out the effects of the portlandite amount in HCP I and HCP III

The mineralogy of air granulated converter slag
Autor: Muhammad Jawad Ahmed Ahmed, Sieger van der Laan, Katrin Schollbach
Publikováno v: International Journal of Ceramic Engineering and Science, 3(1), 21-36. John Wiley and Sons Inc.
Converter slag, also known as Basic Oxygen Furnace slag, is a by-product of steelmaking that is produced in large quantities worldwide. It currently has few applications, because the presence of free lime often prevents the use as aggregate, while th

Enhancing the thermal performance of Class F fly ash-based geopolymer by sodalite
Autor: Katrin Schollbach, Hjh (Jos) Jos Brouwers, Q Qingliang Yu, Kinga Klima
Publikováno v: Construction and Building Materials, 314(Part A):125574. Elsevier
Class F Fly ash-based geopolymers are prone to various high-temperature phenomena, such as cracking, spalling, and thermal shrinkage. Here we study the effect of enriching the Class F fly ash with synthetic sodalite phase in order to enhance the ther

V and Cr substitution in dicalcium silicate under oxidizing and reducing conditions – Synthesis, reactivity, and leaching behavior studies
Autor: Muhammad Jawad, Ahmed, Remco, Cuijpers, Katrin, Schollbach, Sieger, Van Der Laan, Mary, Van Wijngaarden-Kroft, Tiny, Verhoeven, H J H, Brouwers
Publikováno v: Journal of Hazardous Materials, 442:130032. Elsevier
Dicalcium silicate (C2S) is known to incorporate potentially hazardous metals (Cr and V) in a belite-rich cementitious system. The effect of the electrovalence nature of V and Cr on C2S polymorphs’ (α´, β, γ) stability under oxidizing and reduc

Materials
The traditional approach for evaluating capillary imbibition, which describes the phenomena as a linear relationship between mass gain and the square root of time, considers a rigid pore structure. The common deviation from the linearity when using t
